Prof. Jihad Souissi | Orthogonal Polynomials | Young Scientist Award

Faculty of Sciences at Gabes | Tunisia

Prof. Jihad Souissi is a mathematician specializing in orthogonal polynomials, semi-classical structures, and operator-based characterizations, with particular expertise in Dunkl and q-Dunkl operators. His research advances the analytic and algebraic understanding of classical, semi-classical, and q-orthogonal polynomial families through raising and lowering operators, structure relations, differential and difference equations, and operator transformations. He has authored numerous peer-reviewed publications across high-ranking journals, contributing new theoretical frameworks for polynomial characterization, zero-centroid analysis, Appell and q-Appell structures, coherent pairs, and connections between major orthogonal polynomial sequences such as Laguerre, Jacobi, Hermite, and ultraspherical polynomials. His work also explores applications of operator methods to problems in mathematical physics, including boundary-flux control and Stefan-type free boundary problems. In addition to published research, he has produced several preprints expanding semi-classical theory and Dunkl-based formulations. He has presented his findings at international mathematical conferences and seminars and co-edited a scholarly book on orthogonal polynomials and Dunkl operators. Prof. Souissi also serves as a reviewer for multiple international journals, reflecting his active engagement in the global mathematical research community.
