More Reduced Obstruction Theories

Algebraic Geometry 2012-09-21 v1

Abstract

This short note first develops a general formalism for globally removing a factor from an obstruction theory. This formalism is then applied to give a construction of a reduced obstruction theory on the moduli of maps from a curve to a surface satisfying a technical condition. This condition was recently identified in work of Kool and Thomas.
