Let F be a finite field or a p-adic field. One method of constructing irreducible representations of G = GL_2(F), is to consider spaces on which G naturally acts and look at the representations arising from invariants of these spaces, such as cohomology groups. In this talk, I will discuss how this is done for abstract representations of G (when F is finite), and smooth representations of G (when F is p-adic). The first space is an affine algebraic variety, and the second a tower of rigid spaces. I will then mention some recent results about how this tower allows us to construct new interesting p-adic representations of G, before explaining how trying to adapt these methods leads naturally to considerations about certain geometric properties of these spaces.
