Automorphisms of the Complex of
Separating Curves in Genus 3
John D. McCarthy
(This is joint work with Bill Vautaw.) In their
paper, "Commensurations of the Johnson kernel", Brendle-Margalit proved
that every automorphism of the complex of separating curves,
Cs(S), of a closed oriented surface S of genus
at least 4 is induced by a self-homeomorphism of S. In
this series of talks, we outline a proof of the same statement for a closed
oriented surface S of genus 3, which proof can be adapted
to genus at least 3.
