We prove a surgery formula for the smooth Yamabe invariant σ(M) of a compact manifold M. Assume that N is obtained from M by surgery of codimension at least 3. We prove the existence of a positive number Λn, depending only on the dimension n of M, such that σ(N) ≥ min{σ(M),Λn}.

Typo in printed version
At the end of section 1.4, the index *≥3 should be replaced by *≥5
at several locations. The whole section is only valid for dimension
at least 5, which was repeated at various places, and which applies also
to the end of secion 1.4.
