Connected sums with HP^n or CaP^2 and the Yamabe invariant

Chanyoung Sung

Let $M$ be a smooth closed $4 k$ -manifold whose Yamabe invariant $Y (M)$ is nonpositive. We show that $Y (M ♯ l H P^{k} ♯ m H P^{k} ˉ) = Y (M),$ where $l, m$ are nonnega…

Surgery, Yamabe invariant, and Seiberg-Witten theory

Chanyoung Sung

By using the gluing formula of the Seiberg-Witten invariant, we compute the Yamabe invariant Y(X) of 4-manifolds X obtained by performing surgeries along points, circles or tori on…
