Abstract

We study the discrete Painlevé equations associated to the E7(1) affine Weyl group which can be obtained by the implementation of a special limits of E8(1)-associated equations. This study is motivated by the existence of two E7(1)-associated discrete both having a double ternary dependence in their coefficients and which have not been related before. We show here that two equations correspond to two different limits of a E8(1)-associated discrete Painlevé equation. Applying the same limiting procedures to other E8(1)-associated equations we obtained several E7(1)-related equations most of which have not been previously derived.
