From Toda Hierarchy to KP Hierarchy
Di Yang, Jian Zhou
Using the matrix-resolvent method and a formula of the second-named author on the -point function for a KP tau-function, we show that the tau-function of an arbitrary solution t…

A Formula for Connected Bosonic \(n\)-Point Functions for the BKP Hierarchy
Xuhui Zhang, Jian Zhou
We present a formula for the connected \(n\)-point functions of a tau-funtion of the BKP hierarchy by embedding BKP hierarchy into KP hierarchy. This formula is different from the…
