On determinantal formulas for hermitian random matrices

Di Yang, Jiayi Zhao, Jian Zhou

In this paper, we give a direct proof of determinantal formulas for connected -point functions for hermitian matrix models. We also give a new proof of KP integrability for them…

On enumeration of -angulations of surfaces from an integrability perspective

Elba Garcia-Failde, Jianghao Xu, Di Yang +1

In this paper, we study generating series enumerating polygonal angulations of closed oriented surfaces of fixed genus, focusing on -angulations with or , $ν\geq…

On uniform large genus asymptotics of Witten's intersection numbers

Jindong Guo, Di Yang, Don Zagier

Following ideas from [14], we give a uniform large genus asymptotics for primitive psi-class intersection numbers on the moduli space of stable algebraic curves, and extend this re…

Mapping partition functions

Di Yang, Don Zagier

We introduce an infinite group action on partition functions of WK type, meaning of the type of the partition function in the famous result of Witten and Kontsevich ex…

The constrained KP hierarchy and the bigraded Toda hierarchy of -type

Ang Fu, Di Yang, Dafeng Zuo

In this paper, we extend the matrix-resolvent method to the study of the Dubrovin--Zhang type tau-functions for the constrained KP hierarchy and the bigraded Toda hierarchy of $(M,…

On a new proof of the Okuyama--Sakai conjecture

Di Yang, Qingsheng Zhang

In [41] Okuyama and Sakai gave a conjectural equality for the higher genus generalized Brézin--Gross--Witten (BGW) free energies. In a recent work [46] we established the Hodge-BGW…
