On the classification of two dimensional flows
(Universidade Federal de São Carlos, 2023-08-02)
Lawrence Markus, a well-known mathematician, published, in 1954, a strong result about classification of planar vector fields. Afterwards, Dean Arnold Neumann generalized such work for continuous flows, and the result ...
Estabilidade assintótica global para equações diferenciais no plano
(Universidade Federal de São Carlos, 1999-05-25)
Let x! = f(x) be a system of differential equations in the plane where / is C1. This work gives sufficient conditions which guarantee that the basin of attraction of an equilibrium point is the plane. This monograph reports ...
Distribuições suportadas em um hiperplano e o espaço de Hardy hp(Rn)
(Universidade Federal de São Carlos, 2015-08-26)
The main aim of this work is to study necessary and sufficient conditions for a distribution, whose compact support is contained in a hyperplane, to be in the local Hardy space hp(Rn).
