Some glueing formulas for spin polynomials and a proof of the Van de Ven conjecture

Abstract

We deduce some formulas for the spin invariants of the connected sum of an arbitrary 4-manifold X, b^+ _2(X) > 0 $with$\overline {CP^2}$intermsofthespininvariantsof$X$ and apply this to prove the Van de Ven conjecture.
