Kuga-Satake construction and cohomology of hyperkähler manifolds
No full textLet M be a simple hyperkähler manifold. Kuga-Satake construction gives an embedding of into the second cohomology of a torus, compatible with the Hodge structure. We construct a torus T and an embedding of the graded cohomology space for some l, which is compatible with the Hodge structures and the Poincaré pairing. Moreover, this embedding is compatible with an action of the Lie algebra generated by all Lefschetz -triples on M
Procedimentos básicos para colheita de sangue em peixes.
No full textO monitoramento do estado de saúde dos peixes é imprescindível para o manejo sanitário da produção, seja de grande ou pequeno porte. A hematologia clínica é uma ferramenta que permite a realização de diagnóstico de patologias e pode atuar como um indicador prognóstico das condições patológicas, especialmente quando se considera as alterações morfológicas nas células sanguíneas (SATAKE et al., 2009). Estas avaliações permitem identificar a resposta dos peixes, quando doentes, de maneira rápida, prática e de baixo cust
Satake-Furstenberg compactifications, the moment map and \lambda_1
No full textLet G be a complex semisimple Lie group, K a maximal compact
subgroup and an irreducible representation of K on V.
Denote by M the unique closed orbit of G in PP(V) and by
OO its image via the moment map. For any measure \mu on M
we construct a map from the Satake compactification of G/K
(associated to V) to the Lie algebra of K. We call this map, Bourguignon-Li-Yau map since it was introduced by them in the case the complex projective space.
If \mu is the K-invariant measure, then the Bourguignon-Li-Yau map is a homeomorphism of the Satake compactification onto the convex
envelope of OO. For a large class of measures the image of
Bourguignon-Li-Yau map is the convex envelope. As an application we get sharp upper
bounds for the first eigenvalue of the Laplacian on functions for a arbitrary K\"ahler metric on a Hermitian symmetric space

Equivariant Schubert calculus and geometric Satake
No full textThe main classical result of Schubert calculus is that multiplication rules for the basis of Schubert cycles inside the cohomology ring of the Grassmannian are the same as multiplication rules for the basis of Schur polynomials in the ring of symmetric polynomials. In this paper, we explain how to recover this somewhat mysterious connection by using the geometric Satake correspondence to put the structure of a representation of on and comparing it to the Fock space representation on symmetric polynomials. This proof also extends to equivariant Schubert calculus, and gives an explanation of the relationship between torus-equivariant cohomology of Grassmannians and double Schur polynomials.10 page

Construction of the di(trimethylolpropane) cross linkage and the phenylnaphthalene structure coupled with selective β-O-4 bond cleavage for synthesizing lignin-based epoxy resins with a controlled glass transition temperature
No full textLignin, the most abundant aromatic polymer in nature, is a potential renewable source for aromatic compounds in a post-oil era. Lignin is a prospective raw feedstock for epoxy resins because of its phenolic hydroxyl group, which offers a reaction point for glycidylation. However, precisely controlling the physical properties of a lignin-based epoxy resin based on the structure-property relationship is difficult because lignin is a heterogeneous macromolecule with unclarified substructures. The degradation of lignin into its monomers and their subsequent use as a building block for epoxy resins is another possible synthetic route, but this approach suffers from the formation of a wide variety of products by the chemical degradation of lignin. Herein, we successfully demonstrate that the selective degradation of lignin into the C2-acetal monomer by solvolysis in a hydrophobic solvent, i.e., toluene, containing methanolic H2SO4 and the subsequent synthesis of a cross-linked structure through the phenol units of C2-acetal enabled the rational control of the thermodynamic properties of a lignin-based epoxy resin. To introduce a flexible structure into the lignin-based epoxy resin, the transacetalization of C2-acetal with di(trimethylolpropane) (DTMP) was performed to obtain epoxy-DTMP-lignin. For comparison, we introduce a rigid structure by the annulation of C2-acetals to obtain epoxy-annulated lignin. The glass transition temperatures of epoxy-DTMP-lignin and epoxy-annulated lignin obtained by differential scanning calorimetry were 94 °C and 134 °C, respectively, demonstrating the achievement of the precise thermodynamic properties of lignin-based epoxy resins expected based on their structural design
