The mapping class group and the Meyer function for plane curves

  • Yusuke KunoEmail author


For each d ≥ 2, the mapping class group for plane curves of degree d will be defined and it is proved that there exists uniquely the Meyer function on this group. In the case of d = 4, using our Meyer function, we can define the local signature for four-dimensional fiber spaces whose general fibers are non-hyperelliptic compact Riemann surfaces of genus 3. Some computations of our local signature will be given.
