DOI: 10.1007/s10468-019-09871-x

Abstract: We prove several results concerning quasi-bialgebra morphisms D ω ( G ) → D η ( H ) ${\mathcal {D}^{\omega }(G)\to \mathcal {D}^{\eta }(H)}$ of twisted group doubles. We take a particular focus on the… read more here.

DOI: 10.1016/j.topol.2019.107042

Abstract: We say that two classes of topological spaces are equivalent if each member of one class has a homeomorphic copy in the other class and vice versa. Usually when the Borel complexity of a class… read more here.
