Abstract

Three qq-Painlev\'e type equations are derived through degenerations of the qq-Painlev\'e equation with affine Weyl group symmetry of type qq-E8(1)E_8^{(1)}. The three qq-Painlev\'e type equations are associated with different realizations of the same symmetry/surface type qq-E7(1)E_7^{(1)}/qq-A1(1)A_1^{(1)}. We give three representations of affine Weyl group actions of type qq-E7(1)E_7^{(1)}, and relations among them. The three qq-E7(1)E_7^{(1)} equations are also derived from the three representations respectively.
