Two Coefficients of the Dyson Product

Lun Lv, Guoce Xin, Yue Zhou

In this paper, the closed-form expressions for the coefficients of $\frac{x _{r}^{2}}{x _{s}^{2}}$ and $\frac{x _{r}^{2}}{x _{s} x _{t}}$ in the Dyson product are found by applying an extension of Good'…

A Unified Elementary Approach to the Dyson, Morris, Aomoto, and Forrester Constant Term Identities

Ira M. Gessel, Lun Lv, Guoce Xin +1

We introduce an elementary method to give unified proofs of the Dyson, Morris, and Aomoto identities for constant terms of Laurent polynomials. These identities can be expressed as…
