Simple Current Extensions and Mapping Class Group Representations
Peter Bantay
TL;DR
This paper explores the relationship between mapping class group representations and fixed point resolution in simple current extensions, providing a cohomological interpretation of the untwisted stabilizer to deepen understanding of their connection.
Contribution
It offers a cohomological framework for understanding fixed point resolution in simple current extensions and clarifies the relation to mapping class group representations.
Findings
Cohomological interpretation of the untwisted stabilizer
Insight into the conjecture by Fuchs, Schellekens, and Schweigert
Enhanced understanding of simple current extensions and mapping class groups
Abstract
The conjecture of Fuchs, Schellekens and Schweigert on the relation of mapping class group representations and fixed point resolution in simple current extensions is investigated, and a cohomological interpretation of the untwisted stabilizer is given.
