Hopf algebras are determined by their monoidal derived categories

Yuying Xu, Junhua Zheng

We show that two finite-dimensional Hopf algebras are gauge equivalent if and only if their bounded derived categories are monoidal triangulated equivalent. More generally, a monoi…

A correspondence and distance of t-structures

Junhua Zheng

For two t-structures $D_{1} = (D_{1}^{⩽ 0}, D_{1}^{⩾ 1})$ and $D_{2} = (D_{2}^{⩽ 0}, D_{2}^{⩾ 1})$ with $D_{1}^{\leqslant 0} \subseteq D_{2}^{\leqslant 0}…
