In this paper we derive the nonlinear recurrence relation for the recursion coefficients @b"n of polynomials orthogonal with respect to q-analogues of Freud exponential weights. An asymptotic relation for @b"n is given under assuming a certain smoothing condition and the Plancherel-Rotach asymptotic for the corresponding orthogonal polynomials is derived. Special interest is paid to the case m=2. We prove that the nonlinear recurrence relation of @b"n in this case obeys the discrete Painleve property. Motivated by Lew and Quarles, we study possible periodic solutions for a class of nonlinear difference equations of second order. Finally we prove that the Bernstein approximation problem associated to the weights under consideration has a positive solution. |
