W algebra and eigenvalues of the low-order string constraint operators for the discrete KP hierarchy

Firstly, for any p∈N, the string constraint operators without the redundant variables are calculated, which are imposed by the string equation on the τ-function of the p-reduced discrete Kadomtsev–Petviashvili (dKP) hierarchy. Furthermore, the commutators of the string constraint operators without t...
