Fixed points of a finite subgroup of the plane Cremona group

Algebraic Geometry 2016-01-05 v2

Abstract

We classify all finite subgroups of the plane Cremona group which have a fixed point. In other words, we determine all rational surfaces X with an action of a finite group G such that X is equivariantly birational to a surface which has a G-fixed point.
