1. Linearização de aplicações multilineares contínuas entre espaços de Banach e multi-ideais de composição / Linearization of continuous multilinear mappings between Banach spaces and composition multi-ideals
The rst aim of this dissertation is to construct the tensor product of nitely many linear spaces from elementary tensors and to show that this is the space through which multilinear mappings can be linearized. Next continuous multilinear mappings between Banach spaces are studied. The projective norm is introduced in the tensor product in order to perform th

2. Tau(p;q)-summing and sigma(p)-nuclear mappings / Aplicações tau(p;q)-somantes e sigma (p)-nucleares
Neste trabalho estendemos os conceitos de operadores ?-somantes e ?-nucleares apresentados por Pietsch em seu livro Operator Ideals, para aplicações multilineares, polinômios e funções holomorfas, estabelecendo uma relação de dualidade entre os mesmos. Apresentamos também um teorema de dominação para aplicações e polinômios ? (p; q)-somantes, mo

3. Multiplier operator algebras and applications
The one-sided multipliers of an operator space X are a key to “latent operator algebraic structure” in X. We begin with a survey of these multipliers, together with several of the applications that they have had to operator algebras. We then describe several new results on one-sided multipliers, and new applications, mostly to one-sided M-ideals.

4. Traces, ideals, and arithmetic means
This article grew out of recent work of Dykema, Figiel, Weiss, and Wodzicki (Commutator structure of operator ideals) which inter alia characterizes commutator ideals in terms of arithmetic means. In this paper we study ideals that are arithmetically mean (am) stable, am-closed, am-open, soft-edged and soft-complemented. We show that many of the ideals in th
