Hochschild Cohomology, Modular Tensor Categories, and Mapping Class Groups II
Simon Lentner, Svea Nora Mierach, Christoph Schweigert +1
In the first part of this work, we have, for a not necessarily semisimple modular category, generalized the action of the mapping class groups of surfaces on the spaces of conforma…
Hochschild Cohomology, Modular Tensor Categories, and Mapping Class Groups
Simon Lentner, Svea Nora Mierach, Christoph Schweigert +1
Given a finite modular tensor category, we associate with each compact surface with boundary a cochain complex in such a way that the mapping class group of the surface acts projec…
Hochschild Cohomology and the Modular Group
Simon Lentner, Svea Nora Mierach, Christoph Schweigert +1
It has been shown in previous work that the modular group acts projectively on the center of a factorizable ribbon Hopf algebra. The center is the zeroth Hochschild cohomology grou…
