报告摘要： A celebrated conjecture due to Yang Han says that if the Hochschild homology groups of a finite dimensional algebra vanish for sufficiently large degrees, then this algebra is of finite global dimension. We reduce this conjecture to derived 2-simple algebras. We also present some improvements of recent recent results of Cibils et al..This is a joint work in progress with Xiaoxiao Xu and Jinbi Zhang.
