A local signature for fibrations with a finite group action

Masatoshi Sato

Published 2009-12-10Version 1

Let p be a finite regular covering on a 2-sphere with at least three branch points. In this paper, we construct a local signature for the class of fibrations whose general fibers are isomorphic to the covering p.
