1. Tipo e cotipo de espaços de Banach e espaços Lp de Banach / Type and cotype of Banach spaces and Lp-spaces
In this work we study two topics: the basic theory of type and cotype and the Lp-spaces theory. We show that each Lr -space, 1 · r <1; has type min fr; 2g and cotype max fr; 2g. We also prove that no infinite dimensional L1 -space can have type >1 and cotype <1. We detail the study of the Khintchine and Kahane inequalities, needed in order to have full unde

2. Sistemas impulsivos com retardamento: soluções periódicas. / Periodic solutions of an impulsive differential system with delay: an Lp approach.
We prove the existence of periodic solutions of some retarded functional differential equations subjected to impulsive self-supporting conditions. Due to the impulses, solutions exhibit discontinuites of the first kind and this forces the consideration of more general phase spaces than C([-r,0],Rn). We show that periodic solutions can emanate from the origin
