Algebras de operadores Toeplitz

Ordoñez Delgado, Bartleby January 2015 (has links)
En este trabajo examinamos los C*-algebras de operadores Toeplitz sobre la bola unitaria en Cn y en el polidisco unitario en C². Los operadores Toeplitz son ejemplos interesantes de operadores que no son operadores normales y que generan C*-algebras no conmutativas. Además, en los mejores casos de álgebras de operadores Toeplitz (dependiendo de la geometría del dominio) podemos recuperar algunos resultados análogos al teorema espectral módulo operadores compactos. En este contexto, podemos capturar el índice de un operador Fredholm que es un invariante numérico fundamental en Teoría de Operadores / In this work we examine C*-algebras of Toeplitz operators over the unit ball inCn and the unit polydisc in C². Toeplitz operators are interesting examples of non-normal operators that generate non-commutative C*-algebras. Moreover, in the nice cases (depending on the geometry of the domain) of algebras of Toeplitz operators we can recover some analogues of the spectral theorem up to compact operators. In this setting, we can capture the index of a Fredholm operator which is a fundamental numerical invariant in Operator Theory.
