On the Wu classes of the topological blow up

Algebraic Topology 2011-07-08 v2

Abstract

We mainly discuss the Wu classes v(M)v(M) and the Steenrod operation SqSq of the topological blow up M~\tilde{M}. The formula of the Wu class v(M~)v(\tilde{M}) will be given as well as the formula of the Steenrod operation SqSq. As an application, we will use our results to describe a geometric obstruction.
