Exploramos resultados relacionados às curvaturas da variedade Riemanniana subjacente a um grupo de Lie através do estudo de sua álgebra de Lie correspondente. No contexto da geometria Hermitiana e geometria Kähler, para um caso concreto de grupo de Lie complexo, investigaram suas curvaturas seccionais holomorfas e verificamos a existência de uma estrutura pseudo-Kähler invariante por sua forma real compacta / Abstract: In this dissertation, we study the geometric aspects of Lie groups from the viewpoint of Riemannian geometry, Hermitian geometry, and Kähler geometry through its associated invariant geometric structures. We explore results related to curvatures of Riemannian manifold underlying a Lie group by studying its corresponding Lie algebra. In the context of Hermitian geometry and Kähler geometry, for a complex Lie group case, we investigate its holomorphic sectional curvatures and verify the existence of pseudo-Kähler structure invariant for its compact real form / Mestrado / Matematica / Mestre em Matemática

In this thesis I describe construction of Lie group and Lie algebra and its following usage for physical problems. To be able to construct Lie groups and Lie algebras we need define basic terms such as topological manifold, tensor algebra and differential geometry. First part of my thesis is aimed on this topic. In second part I am dealing with construction of Lie groups and algebras. Furthermore, I am showing different properties of given structures. Next I am trying to show, that there exists some connection among Lie groups and Lie algebras. In last part of this thesis is used just for showing how this apparat can be used on physical problems. Best known usage is to find physical symmetries to establish conservation laws, all thanks to famous Noether theorem.
