Título: Inessential operators, perturbation classes and incomparability of Banach spaces
Resumo: Inessential operators appeared as the perturbation class for Fredholm operators, and were applied to define a notion of incomparability of Banach spaces.
In this talk we begin by introducing the inessential operators. Then we review the perturbation classes problem for Fredholm and semi-Fredholm operators, and present several notions of incomparability of Banach spaces emphasizing the one associated to the inessential operators.
