Surface groups, Artin groups, and their representations

We will discuss the connections between the geometry of two-dimensional surfaces and certain representations of their fundamental groups into various Lie groups. We will also describe the relationship between surface groups and right-angled Artin groups, and explain how this plays a key role in allowing us to construct explicit examples of such representations.
