摘 要:
In this talk, we study the Gelfand-Kirillov dimension (GK-dimension) of operads and its applications. In particular, analogues of Bergman’s gap theorem are proved for nonsymmetric and symmetric operads, namely, no finitely generated locally finite nonsymmetric (resp., symmetric) operad has GK-dimension strictly between 1 and 2. On the contrary, for an arbitrary real number r\geq 1, there exist shuffle operads of GK-dimension r. This is a joint work with Yu Li, Zihao Qi, Yongjun Xu, James Zhang, and Zerui Zhang.
