Pseudo-isotopy classes of diffeomorphisms of the unknotted pairs $(S^{n+2},S^n)$ and $(S^{2p+2},S^p\times S^p)$

Nikolai A. Krylov

We consider two pairs: the standard unknotted $n$-sphere in $S^{n+2}$, and the product of two $p$-spheres trivially embedded in $S^{2p+2}$, and study orientation preserving diffeom…
