String equations of the q-KP hierarchy

Abstract

Based on the Lax operator L and Orlov-Shulman’s M operator, the string equations of the q-KP hierarchy are established from the special additional symmetry flows, and the negative Virasoro constraint generators {L _−n, n ≥ 1} of the 2-reduced q-KP hierarchy are also obtained.

Keywords
