A remark on the η-invariant for automorphisms of hyperelliptic Riemann surfaces

Research output: Contribution to journal › Article

Abstract

We give a characterisation for the vanishing of the η-invariant of prime order automorphisms of hyperelliptic Riemann surfaces through the mapping torus construction. To this end, we introduce a notion of s-symmetry for finite order surface automorphisms.
