On the 3-Dimensional Poincaré Conjecture and the 4-Dimensional Smooth Schoenflies Problem

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/120298This is the announcement of an alternative approach to the 3-dimensional Poincaré Conjecture, different from Perelman's big and spectacular breakthrough. No claim concerning the other parts of the Thurston Geometrization Conjecture, come with our purely 4-dimensional line of argument.Geometric Topology57M10,57M40,57N60,57Q10,57R65On the 3-Dimensional Poincaré Conjecture and the 4-Dimensional Smooth Schoenflies Problemtext
