Abstract in Portuguese
O principal objetivo deste trabalho é estudar diversas aplicações de combinatória infinita em espaços de funções contínuas, definidas em espaços compactos Hausdorff. Usando combinatória infinita para uma álgebra de Boole, por meio da dualidade de Stone, obtemos um espaço compacto Hausdorff. Com certas propriedades na álgebra de Boole é possível analisar propriedades analíticas no espaço de funções contínuas definidas em tal espaço. Especificamente, analisamos a propriedade de Grothendieck. Também analisamos a relação entre o espaço de funções contínuas e o espaço compacto Hausdorff sobre o qual é definido. Apresentamos um resultado que permite obter diversos resultados conhecidos de uma maneira uniforme (só usando fatos de topologia e teoria de conjuntos), dotando o espaço de funções contínuas de uma ordem peculiar. Finalmente, estudamos um pouco de jogos topológicos mediante diversos exemplos.

Abstract in English
The main purpose of this work is to study some infinite combinatorics applications in spaces of continuous functions, defined in Hausdorff compact spaces. Using infinite combinatorics in Boolean algebras, through Stone duality, we obtain a compact Hausdorff space. With certain properties in Boolean algebras it is possible to analyze analytic properties in the space of continuous functions defined in such space. Specifically, we analyze the Grothendieck property. We also analyze the relationship between the space of continuous functions and the compact Hausdorff space on which it is defined. We present a result that allows to obtain several known results in a uniform way (only using facts of topology and set theory), giving the space of continuous functions a peculiar order. Finally, we study some topological games through several examples.
