报告摘要: In this talk, I will first give an overview of combinatorics on maps and hypermaps which is a topic lying at the crossroad of several research fields such as topology, algebraic geometry and mathematical physics. Then, I will report some of our recent work on the subject, including a unified approach for proving the celebrated Harer-Zagier formula, Jackson’s formula for one-face hypermaps, and explicit formulas for the genus distribution polynomials for two-face hypermaps and their log-concavity.
