Hurwitz number and intersection on modular
Websphere and the intersection theory on moduli spaces allows us to prove that some natural generating functions enumerating the ramified cov-erings lie, yet again, in A. As an application, one can find the asymp-totic of the number of such coverings as the number of sheets tends to ∞. We believe that the leading terms of the asymptotics like that Web12 aug. 2024 · Hurwitz numbers (in many variants) appeared at the cross-road of many active directions in contemporary mathematics and mathematical physics, such as the combinatorics of symmetric groups and graphs on surfaces, the intersection theory in algebraic geometry, tau functions in integrable systems and tropical geometry (see, for …
