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\g…

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…

Combinatorics and large genus asymptotics of the Brézin--Gross--Witten numbers
Jindong Guo, Paul Norbury, Di Yang +1
In this paper, we study combinatorial and asymptotic properties of some interesting rational numbers called the Brézin--Gross--Witten (BGW) numbers, which can be represented as th…
