Title: Positive Tropicalization of Character Varieties

Abstract: I will start by defining framed character varieties for a surface S and the group SL_n. Then I will introduce the notion of a cluster algebra and describe the cluster structure on the framed character variety. This allows us to define the positive tropicalization of the character variety. I will end by giving many examples of how to explicitly write down tropical points of the character variety using the affine Grassmannian.
