Two Coefficients of the Dyson Product

Lun Lv, Guoce Xin, Yue Zhou

Abstract


In this paper, the closed-form expressions for the coefficients of ${x_r^2\over x_s^2}$ and ${x_r^2\over x_sx_t}$ in the Dyson product are found by applying an extension of Good's idea. As consequences, we find several interesting Dyson style constant term identities.
