Abstract: Culler, Morgan, and Shalen pioneered the detection essential surfaces in 3- manifolds through SL(2, C) character varieties. I’ll review these character varieties and detection, then discuss how symmetries of the 3-manifold affect this detection before concluding with some examples. This is joint work with Jay Leach.
