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.

Hurwitz 数的平方根

我们展示了类似于(断开连接的)双 Hurwitz 数的自旋 Hurwitz 数的生成函数,它是双分量 BKP (2-BKP) 层次结构的 tau 函数,并且是双分量 KP 的 tau 函数的平方根( 2-KP) 层次结构由相关的 Hurwitz 数定义。
