Sistemas afins e bilineares em grupos de Lie

Abstract

This thesis is composed of two parts. Initially we give some preliminary aspects about linear vector fields on Lie Groups. For the second one, we analyze the relationship between affine systems on Lie groups and their induced bilinear systems. We prove that the solutions of affine systems are given by left translation of the solutions of the induced bilinear system by the solution on the identity, which allow us to conclude some con-trollability results by using geometric properties. Moreover, we present a linear vector field on tree-dimensional sovable Lie group. This vector field is analytic on a Lie group, does not necessarily needs to be polinomial, in the sense that its expression depends on polinomial maps. It was an open problem the existence of a non-polinomial analytic linear vector field
