Martedì 29 Gennaio 2019 alle ore 11:30 in Aula 1C150, Mama Foupouagnigni (Yaoundé, Cameroon) terrà un seminario dal titolo “On difference equations for orthogonal polynomials on special nonuniform lattices”.

Abstract
In this talk, we derive an appropriate polynomial basis which is then used to: 1) provide the functional approach of the characterization theorem for classical orthogonal polynomials on nonuniform lattice; 2) providing algorithmic method to find explicit solution to holonomic divided-difference equation and 3) the derivation of some structure relations for classical orthogonal polynomials on nonuniform lattices such the determination of the coefficients of the connection and the linearisation problems involving classical orthogonal polynomials on nonuniform lattices.
This is a collection of joint works with: Wolfram Koepf (University of Kassel, Germany), Salifou Mboutngam (University of Maroua, Cameroon), Maurice Kenfack-Nangho (University of Dschang, Cameroon), Daniel Duviol Tcheutia (University of Kassel, Germany) and Patrick Njionou Sadjang (University of Douala, Cameroon).
