Title in Portuguese
Tópicos sobre campos de gauge a temperatura finita.
Keywords in Portuguese
Campos de gauge
Abstract in Portuguese
Após uma breve revisão sobre tópicos básicos de teorias de gauge, apresentaremos resultados relacionados a um conjunto de trabalhos que tratam do formalismo de teoria de campos a temperatura finita aplicada ao estudo de teorias de gauge. A ênfase será mais especifimente nos trabalhos sobre a versão não-comutativa destas teorias. Um dos principais objetivos destes trabalhos é a investigação fenômenos no limite de altas temperaturas em termos de uma ação efetiva invariante de gauge. Concluiremos com uma breve discussão sobre a possibilidade de se introduzir a não-comutatividade em presença das interações gravitacionais.

Abstract in English
After a brief review of basic topics of gauge theories, we present results related to a series of works dealing with the formalism of field theory at finite temperature applied to the study of gauge theories. The emphasis will be especifimente in work on non-commutative version of these theories. A major objective of this work is to investigate phenomena in the limit of high temperatures in terms of a gauge invariant effective action. We conclude with a brief discussion about the possibility of introducing non-commutativity in the presence of gravitational interactions.
