$q$-Middle Convolution and $q$-Painlevé Equation
Published 11 Jan 2022 in math.CA, math-ph, and math.MP | (2201.03960v2)
Abstract: A $q$-deformation of the middle convolution was introduced by Sakai and Yamaguchi. We apply it to a linear $q$-difference equation associated with the $q$-Painlev\'e VI equation. Then we obtain integral transformations. We investigate the $q$-middle convolution in terms of the affine Weyl group symmetry of the $q$-Painlev\'e VI equation. We deduce an integral transformation on the $q$-Heun equation.
