报告摘要: we introduce the notion of quantum-symmetric equivalence of two connected graded algebras, based on Morita-Takeuchi equivalences of universal quantum groups. In particular, we give a way of deforming a connected graded algebra which preserves its quantum symmetric class. As an application, we show every Zhang twist of a m-homogenous graded algebra is a 2-cocycle twist.
