In this framework, we prove the Heine's relations and a connection formula for the q-hypergeometric function of the Barnes type. We also prove an orthogonality relation of the q-little Jacobi polynomials at |q|=1.16 pagesQuantum AlgebraClassical Analysis and ODEsThe q-twisted cohomology and the q-hypergeometric function at |q|=1text
