On the formal ribbon extension of a quasitriangular Hopf algebra
Quinn T. Kolt
Any finite-dimensional quasitriangular Hopf algebra can be formally extended to a ribbon Hopf algebra of twice the dimension. We investigate this extension and its r…

Modular data of non-semisimple modular categories
Liang Chang, Quinn T. Kolt, Zhenghan Wang +1
We investigate non-semisimple modular categories with an eye towards a structure theory, low-rank classification, and applications to low dimensional topology and topological physi…

Indecomposable Hopf -algebra representations with invariant inner product
Quinn T. Kolt, Ziqian Zhao
We generalize a result of Araki (1985) on indecomposable group representations with invariant (necessarily indefinite) inner product and irreducible subrepresentation to Hopf -a…
