Ideal Classes and Cappell-Shaneson Homotopy 4-Spheres

Min Hoon Kim∗, Shohei Yamada

Kyungpook Mathematical Journal 2023; 63: 373-411

Gompf proposed a conjecture on Cappell-Shaneson matrices whose affirmative answer implies that all Cappell-Shaneson homotopy 4-spheres are diffeomorphic to the standard 4-sphere. We study Gompf conjecture on Cappell-Shaneson matrices using various al...
