An intersection theory count of the -representations of the fundamental group of a 3-manifold

Curtis, Cynthia (Elsevier, 2001)

We define an invariant of closed 3-manifolds counting the signed equivalence classes of representations of the fundamental group in . The invariant is an -analog of the Casson-Walker invariant for SU(2). We reinterpret the ...
