Stable homotopy invariance of Teichner's sec invariant
Given a notion of equivalence of 4-manifolds, there is a corresponding notion of stable equivalence: M is stably equivalent to N if M#rS2 x S2 is equivalent to N# sS2 x S2 for some non-negative integers r, s. Any equivalence relation which extends over an S2 x S2 summand gives a well-defined equiva...
