Asymptotic analysis of difference equations with quadratic coefficients
Pages: 155 – 172
In this paper, we study asymptotic solutions of second-order difference equations with quadratic coefficients. According to the parameter values, we classify the difference equations into three cases and derive Plancherel–Rotach type asymptotic formulas of the solutions respectively. As direct applications of our main results, we also provide asymptotic formulas of associated Meixner–Pollaczek polynomials, associated Meixner polynomials, and associated Laguerre polynomials, respectively.
