On the classification of finite GK-dimensional pre-Nichols algebras and quasi-quantum groups
Yuping Yang
We prove that every pre-Nichols algebra of a nondiagonal object in the twisted Yetter-Drinfeld category ${_{\k G}^{\k G} {\mathcal{YD}^Φ}}$ has infinite Gelfand-Kirillov dimension…

Combinatorial equivalence of separable elements in types and
Yong Liao, Yuping Yang, Houyi Yu
We study the combinatorial equivalence of separable elements in types and . A bijection is constructed from the set of separable permutations in the symmetric group $S_{n+1}…
