Sobre as práticas e reflexões publicitárias de Fernando Pessoa
No full textNeste texto, a autora analisa alguns trabalhos publicitários de Fernando Pessoa, bem
como algumas das suas reflexões sobre esta actividade. É dada especial atenção ao slogan
“Primeiro estranha-se. Depois entranha-se”, analisado sobre a perspectiva das funções
e propriedades deste constituinte da mensagem publicitária. Por fim, recorda-se
um recente slogan que recupera o clássico de Fernando Pessoa.
On this article, the author analyses some advertising texts created by Fernando Pessoa and
some of his thoughts about this activity. The main attention goes to the famous slogan “Primeiro
estranha-se. Depois entranha-se”, analysed through the principles of the functions
and proprieties of this element of advertisements. Finally, the author presents a recent slogan, constructed through the slogan of the Portuguese writer
The eigenvalues of limits of radial Toeplitz operators
No full textLet A2 be the Bergman space on the unit disk. A bounded operator S on A2 is called radial if Szn = λnzn for all n 0, where λn is a bounded sequence of complex numbers. We characterize the eigenvalues of radial operators that belong to the Toeplitz algebra.Fil: Suarez, Fernando Daniel. Universitat Autònoma de Barcelona; España.

A counterexample for H ∞ approximable functions
No full textLet D be the unit disk. We show that for some relatively closed set F ⊂ D there is a function f that can be uniformly approximated on F by functions of H∞, but such that f cannot be written as f = h + g, with h ∈ H∞ and g uniformly continuous on F. This answers a question of Stray.Fil: Suarez, Fernando Daniel. Consejo Nacional de Investigaciones Científicas y Técnicas. Oficina de Coordinación Administrativa Saavedra 15.

Localisation techniques for division in Douglas algebras
No full textIn this paper we use uniform algebra techniques and recent results on separation properties to prove several division theorems for closed subalgebras of L∞ containing H∞. We also study ideals having the local approximation property and we show that not every ideal in such algebras is local.Fil: Suarez, Fernando Daniel.

The Toeplitz algebra on the Bergman space coincides with its commutator ideal
No full textLet L^2-a be the Bergman space of the unit disk and T(L^2_a) be the Banach algebra generated by Toeplitz operators T_f , with f ∈ L∞. We prove that the closed bilateral ideal of T(L2a) generated by operators of the form T_fT_g − T_gT_f coincides with T(L^2_a).Fil: Suarez, Fernando Daniel.

As a partial answer to this problem, we prove the result when f 1 is an inner function in Q p .Fil: Pau, Jordi. Universidad de Barcelona; EspañaFil: Suarez, Fernando Daniel.

Estudio jurídico y social del trabajo infantil en el municipio de Suarez –Tolima
No full textEl presente trabajo de grado intentar definir de forma metodológico la influencia del trabajo infantil en los niveles de escolarización de estudiantes del municipio de Suarez Tolima, un municipio que tradicionalmente con alta concentración en producción agrícola, partiendo de esta premura , intenta incentivar el debate sobre los lineamientos de trabajo infantil emitidos en gran proporción por la Organización Internacional del Trabajo, en adelante, O.T.I, los cuales los Estados toman como referencia en el trazado de las políticas públicas para mitigar esta problemática, pero en evidencia hallada, la normativa jurídica está muy distante de la realidad social que niños, niñas y adolescente enfrenta en la cotidianidad en muchas regiones de Colombia. Para poder abordar la problemática jurídica y social de este trabajo se trazó como objetivo general Desarrollar un estudio de caso jurídico y social referente a las condiciones en que desempeñan sus labores los menores de edad inmersos en Trabajo infantil en Suarez - Tolima. Para la obtención y procesamiento de los datos se utilizó un método cualitativo con enfoque de estudio de caso, con una muestra probabilística compuesta por 17 docentes de grados 9,10 y 11 en la institución educativitas del municipio.The present degree work tries to define in a methodological way the influence of child labor in the levels of schooling of students of the municipality of Suarez Tolima, a municipality that traditionally with high concentration in agricultural production, starting from this rush, tries to stimulate the debate on child labor guidelines issued in large proportion by the International Labor Organization, hereinafter, OTI, which states take as a reference in the design of public policies to mitigate this problem, but in evidence found, legal regulations are very distant of the social reality that children and adolescents face in everyday life in many regions of Colombia.
In order to address the legal and social problems of this work, the general objective was to develop a legal and social case study referring to the conditions in which minors under immersion in child labor in Suarez - Tolima perform their duties. To obtain and process the data, a qualitative method with a case study approach was used, with a probabilistic sample composed of 17 teachers of grades 9,10 and 11 in the educational institution of the municipality.Introducción. -- 1.

The Essential Norm of Operators in the Toeplitz Algebra on Ap(Bn)
No full textLet Ap be the Bergman space on the unit ball Bn of Cn for 1 <p< ∞, and Tp be the corresponding Toeplitz algebra. We show that every S ∈ Tp can be approximated by operators that are specially suited for the study of local behavior. This is used to obtain several estimates for the essential norm of S ∈ Tp, an estimate for the essential spectral radius of S ∈ T2, and a localization result for its essential spectrum. Finally, we characterize compactness in terms of the Berezin transform for operators in Tp.Fil: Suarez, Fernando Daniel. Consejo Nacional de Investigaciones Científicas y Técnicas.

Approximation and the n-Berezin transform of operators on the Bergman space
No full textTo any bounded operator S on the Bergman space La2 we associate a sequence of linear transforms Bn(S ) ∈ L∞(D), where n ≧ 0, and prove that the Toeplitz operators article image tend to S for some especial classes of operators S. In particular, this holds for every radial operator in the Toeplitz algebra. Finally, we show that the inclusion of the Toeplitz algebra into the essential commutant of the Bergman shift is proper.Fil: Suarez, Fernando Daniel.
