Title:A square root of Hurwitz numbers

Authors:Junho Lee
View PDF
Abstract:We exhibit a generating function of spin Hurwitz numbers analogous to (disconnected) double Hurwitz numbers that is a tau function of the two-component BKP (2-BKP) hierarchy and is a square root of a tau function of the two-component KP (2-KP) hierarchy defined by related Hurwitz numbers.
Comments: Some minor changes, following the referee's report. To appear in Manuscripta Math
