Existência e multiplicidade de soluções para uma classe de problemas envolvendo operadores fracionários
(Universidade Federal de São Carlos, 2019-08-14)
In this work, we study existence and multiplicity of weak solutions for three problems involving fractional operators, with emphasis on critical growth nonlinearities. The first problem deals with the existence of sign-changing ...
$L^2$ estimates for the operators $ \bar\partial $ and $ \bar\partial_b $
(Universidade Federal de São Carlos, 2019-08-02)
The purpose of this work is to establish sufficient conditions for closed range estimates on $(0,q)$-forms, for some fixed $q$, $1 \leq q \leq n-1$, for $\bar\partial_b$ in both $L^2$ and $L^2$-Sobolev spaces in embedded, ...
Funções Lq ultradiferenciáveis globais e aplicações
(Universidade Federal de São Carlos, 2019-11-20)
The class of global Gevrey functions was introduced recently by Z. Adwan, G. Hoepfner and A. Raich, the elements in these spaces are defined in terms of its derivatives with estimates that depend on sequences. It is know ...
Applications of topological degree theory to generalized ODEs
(Universidade Federal de São Carlos, 2019-10-27)
In this work, we present original results concerning the theory of Generalized Ordinary Differential Equations (we write generalized ODEs for short) using tools from the Topological Degree theory. In particular, we proved ...
