On enumeration of $l$ -hypermaps

Zhengfei Huang, Di Yang

The $l$ -hypermaps, $l \geq 2$ , which generalize (dual of) ribbon graphs ( $l = 2$ case), are interesting enumerative objects. In this paper, based on a theorem of Carlet--van de Leur--Po…

On Gromov--Witten invariants of $P^{1}$ -orbifolds and topological difference equations

Zhengfei Huang, Di Yang

Let $(m_{1}, m_{2})$ be a pair of positive integers. Denote by $P^{1}$ the complex projective line, and by $P_{m_{1}, m_{2}}^{1}$ the orbifold complex projective line obtained…
