Tropical ginsberg: the resonance of Allen Ginsberg on the Tropicália
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-graduação em Letras/Inglês e Literatura Correspondente, Florianópolis, 2010Through a dialogical relation between poems and song lyrics, and the socio-political contexts which surrounded these texts, this research discusses the resonance that North American poet, Allen Ginsberg, had over the Brazilian musical movement, the Tropicália. The corpora are the poems "Howl" (1956), "America" (1956), "Supermarket in California" (1955), "Sunflower Sutra" (1955), "Song" (1954), and "Wild Orphan" (1952), written by Allen Ginsberg, and the songs "Batmacumba" (1968), composed by Caetano Veloso, and Gilberto Gil, "Baby" (1968), composed by Caetano Veloso, "Geléia Geral" (1968), composed by Gilberto Gil and Torquato Neto, "Alegria, Alegria" (1967), composed by Caetano Veloso, and "Domingo no Parque" (1967), composed by Gilberto Gil. The main theoretical and critical parameters of this research include: Mikhail Bakhtin and his reflections on intertextuality; James J. Farrell, who believes that the American counterculture began with the Beats; Claudio Willer, who stresses the importance of Allen Ginsberg to the Beat movement, as well as to the birth of the American counterculture; Christopher Dunn, who emphasizes the historical, social, and political relevance of the Tropicália; and Celso Favaretto, who discusses in depth the complexity of most of the Tropicália songs. Based on such parameters, this research suggests that the life and work of Allen Ginsberg had great resonance over the creation of the Tropicália.Através de uma relação dialógica entre poesia e letras de música e o contexto sócio-político que circundava tais textos, este estudo discute a ressonância que o poeta Norte Americano, Allen Ginsberg, teve sobre o movimento musical Brasileiro, a Tropicália. A corpora são os poemas "Howl" (1956), "America" (1956), "Supermarket in California" (1955), "Sunflower Sutra" (1955), "Song" (1954), e "Wild Orphan" (1952), escritos por Allen Ginsberg, e as músicas "Batmacumba" (1968), composta por Caetano Veloso, e Gilberto Gil, "Baby" (1968), composta por Caetano Veloso, "Geléia Geral" (1968), composta por Gilberto Gil e Torquato Neto, "Alegria, Alegria" (1967), composta por Caetano Veloso, e "Domingo no Parque" (1967), composta por Gilberto Gil. Os principais parâmetros teóricos e críticos desta pesquisa incluem: Mikhail Bakhtin e suas reflexões sobre intertextualidade; James J. Farrell, que acredita que a contracultura Americana começou com os Beats; também em Claudio Willer, que salienta a importância de Allen Ginsberg no movimento Beat e no nascimento da contracultura Americana; Christopher Dunn, que enfatiza a relevância histórica, social e política da Tropicália; e Celso Favaretto, que discute em profundidade a complexidade da grande maioria das músicas da Tropicália. Baseando-se em tais parâmetros identificados, esta dissertação sugere que a vida e obra de Allen Ginsberg tiveram grande ressonância sobre a criação da Tropicália

Schubert puzzles and integrability I: invariant trilinear forms
No full textThe puzzle rules for computing Schubert calculus on -step flag manifolds,
proven in [Knutson Tao 2003] for -step, in [Buch Kresch Purbhoo Tamvakis
2016] for -step, and conjectured in [Coskun Vakil 2009] for -step, lead
to vector configurations (one vector for each puzzle edge label) that we
recognize as the weights of some minuscule representations. The -matrices of
those representations (which, for -step flag manifolds, involve triality of
) degenerate to give us puzzle formulae for two previously unsolved
Schubert calculus problems: -step flag manifolds and -step flag
manifolds. The -step flag manifolds formula, which involves 151 new
puzzle pieces, implies Buch's correction to the first author's 1999 conjecture
for -step flag manifolds.Comment: v5: misleading sentence in the statement of theorem 2 and missing
pictures in the statement of theorem 3 fixed. no results or proofs changed.

Warm Spitzer occultation photometry of WASP-26b at 3.6 and 4.5 mu m
No full textWe present new warm Spitzer occultation photometry of WASP-26 at 3.6 and 4.5 mu m along with new transit photometry taken in the g, r and i bands. We report the first detection of the occultation of WASP-26b, with occultation depths at 3.6 and 4.5 mu m of 0.001 26 +/- 0.000 13 and 0.001 49 +/- 0.000 16 corresponding to brightness temperatures of 1825 +/- 80 and 1725 +/- 89 K, respectively. We find that the eccentricity of the orbit is consistent with a circular orbit at the 1 sigma level (e = 0.0028(-0.0022)(+0.0097), 3 sigma upper limit e < 0.04). According to the activity-inversion relation of Knutson et al., WASP-26b is predicted to host a thermal inversion. The brightness temperatures deduced from the eclipse depths are consistent with an isothermal atmosphere, although the planet may host a weak thermal inversion given the uncertainties on these values. The data are equally well fitted by atmospheric models with or without a thermal inversion. We find that variation in activity of solar-like stars does not change enough over the time-scales of months or years to change the interpretation of the Knutson et al. activity-inversion relation, provided that the measured activity level is averaged over several nights. Further data are required to fully constrain the thermal structure of the atmosphere because the planet lies very close to the boundary between atmospheres with and without a thermal inversion.Peer reviewe
Brick Varieties And Toric Matrix Schubert Varieties
No full textIn the first part of this thesis we study brick varieties which are fibers of the Bott-Samelson varieties. Bott-Samelson varieties are a twisted product of CP1 's with a map into G/B. These varieties are mostly studied in the case in which the map into G/B is birational to the image; however in the first part of this thesis we study a fiber of this map when the map is not birational. We prove that in some cases the general fiber, which we christen a brick variety, is a toric variety. In order to do so we use the moment map of a Bott-Samelson variety to translate this problem into one in terms of the "subword complexes" of Knutson and Miller. Pilaud and Stump realized certain subword complexes as the dual of the boundary of a polytope which generalizes the brick polytope defined by Pilaud and Santos. For a nice family of words, the brick polytope is the generalized associahedron realized by Hohlweg, Lange and Thomas. These stories connect in a nice way: we show that the moment polytope of the brick manifold is the brick polytope. In particular, we give a nice description of the toric variety of the associahedron. We give each brick manifold a stratification dual to the subword complex. In addition, we relate brick manifolds to Brion's resolutions of Richardon varieties. In the second part of this thesis, which is joint work with Karola M´ sz´ ros, e a we show that a family of subword complexes can be realized geometrically via regular triangulations of root polytopes. This implies that a family of Grothendieck polynomials are special cases of reduced forms in the subdivision algebra of root polytopes. We also write the volume and Ehrhart series of root polytopes in terms of -Grothendieck polynomials. Finally, we explain this geometric realization by characterizing the matrix Schubert varieties which are the product of a toric variety and a vector space
A scheme related to the Brauer loop model
No full textAbstractWe introduce the Brauer loop schemeE:={M∈MN(C):M•M=0}, where • is a certain degeneration of the ordinary matrix product. Its components of top dimension, ⌊N2/2⌋, correspond to involutions π∈SN having one or no fixed points. In the case N even, this scheme contains the upper–upper scheme from [A. Knutson, Some schemes related to the commuting variety, J. Algebraic Geom., in press, math.AG/0306275] as a union of (N/2)! of its components. One of those is a degeneration of the commuting variety of pairs of commuting matrices.The Brauer loop model is an integrable stochastic process studied in [J. de Gier, B. Nienhuis, Brauer loops and the commuting variety, J. Stat. Mech. (2005) P01006, math.AG/0410392], based on earlier related work in [M.J. Martins, B. Nienhuis, R. Rietman, An intersecting loop model as a solvable super spin chain, Phys. Rev. Lett. 81 (1998) 504–507, cond-mat/9709051], and some of the entries of its Perron–Frobenius eigenvector were observed (conjecturally) to equal the degrees of the components of the upper–upper scheme.Our proof of this equality follows the program outlined in [P. Di Francesco, P. Zinn-Justin, Inhomogeneous model of crossing loops and multidegrees of some algebraic varieties, math-ph/0412031]. In that paper, the entries of the Perron–Frobenius eigenvector were generalized from numbers to polynomials, which allowed them to be calculated inductively using divided difference operators. We relate these polynomials to the multidegrees of the components of the Brauer loop scheme, defined using an evident torus action on E. As a consequence, we obtain a formula for the degree of the commuting variety, previously calculated up to 4×4 matrices
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
