Finiteness conjecture for symplectic representatives up to smooth isotopy
arXiv@arxiv
Let $X$ be a symplectic 4-manifold and let $\Sigma$ be a symplectic submanifold. Consider symplectic submanifolds $\Sigma'$ that are topologically isotopic to $\Sigma$ . Finiteness…

Let $f\colon S^4\to S^4$ be an orientation-preserving self-diffeomorphism. Smale conjecture, special case. Every orientation-preserving self-diffeomorphism of $S^4$ is smoothly iso…
