Abstract

In the paper we first construct rational solutions for the Nijhoff-Quispel-Capel (NQC) equation by means of bilinear method. These solutions can be transferred to those of Q3δ_\delta equation in the Adler-Bobenko-Suris (ABS) list. Then making use of degeneration relation we obtain rational solutions for Q2, Q1δ_\delta, H3δ_\delta, H2 and H1. These rational solutions are in Casoratian form and the basic column vector satisfies an extended condition equation set.
