Abstract

We prove a surgery formula for the smooth Yamabe invariant $\sigma(M)$ 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 constant $\Lambda_n$, depending only on the dimension n of $M$, such that \[ \sigma(N) \ge \mathrm{min}\{\sigma(M),\Lambda_n\}.\]
