Mutual orthogonality polynomials associated with Poisson distribution / V. N. Sorokin. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2015. № 1. P. 3-8 [Moscow Univ. Math. Bulletin. Vol. 72, N 2, 2017. P. 1-5].
A generalization of orthogonal polynomials of discrete variable, namely, Charlier polynomials is studied. The limit distribution of their zeros is obtained by the saddle-point method.
Key words: Charlier polynomials, saddle-point method.
