Abstract

We solve the discrete Hirota equations (Kirillov-Reshetikhin Q-systems) for A_r , and their analogue for D_r , for the cases where the second variable ranges over either a finite set or over all integers. Until now only special solutions were known. We find all solutions for which no component vanishes, as required in the known applications. As an introduction we present the known solution where the second variable ranges over the natural numbers.
