Abstract
In this talk, we introduce the notion of alterfold invariants and their associated TQFTs. Then we will give several applications including the topological description of the Drinfeld center, the equivalence between the RT- and TV-TQFTs, and the equivariance of the generalized Frobenius-Schur indicators. Finally, we will discuss how to obtain families of Morita invariants as generalizations of the indicators, and speculate some of the potential applications. This is based on joint work with Zhengwei Liu, Shuang Ming and Jinsong Wu.
