报告摘要: 

Using the Virasoro constraints we derive the loop equations for the cubic Hodge partition function with three parameters p, q, r satisfying the Calabi-Yau condition p q + q r + r p = 0. We show that the corresponding Hodge hierarchy is Miura equivalent to the fractional Volterra hierarchy (FVH). In the procedure of the proof, a particular tau-function for the FVH is constructed. When one of the three parameters p, q, r is equal to 1, we also prove a certain gap condition for the logarithm of the particular tau-function. The talk is based on joint works with Boris Dubrovin, Si-Qi Liu, Youjin Zhang and Chunhui Zhou.
