Geometric obstructions for $I^¾$ -fillings of 3-manifolds

Daniel Galvin, Peter Teichner, Simona VeselÃ¡

We consider the realisation problem for normal 1-types of 4-manifolds with a given boundary. More precisely, given a normal 1-type $I^¾$ and closed 3-dimensional $I^¾$ -manifold $Y$ ,…

Algorithms in 4-manifold topology

Stefan Bastl, Rhuaidi Burke, Rima Chatterjee +28

We show that there exists an algorithm that takes as input two closed, simply connected, topological 4-manifolds and decides whether or not these 4-manifolds are homeomorphic. In p…

SKK groups of manifolds and non-unitary invertible TQFTs

Renee S. Hoekzema, Luuk Stehouwer, Simona VeselÃ¡

This work considers the computation of controllable cut-and-paste groups $SKK^{I^} ¾_{n}$ of manifolds with tangential structure $I^¾ : B_{n} \to B O_{n}$ . To this end, we apply the work…
