On the Pontrjagin-Viro form

alg-geom 2008-03-21 v1 Algebraic Geometry

Abstract

A new invariant, the Pontrjagin-Viro form, of algebraic surfaces is introduced and studied. It is related to various Rokhlin-Guillou-Marin forms and generalizes Mikhalkin's complex separation. The form is calculated for all real Enriques surfaces for which it is well defined.
