Iberian Online Analysis Seminar

The Iberian Online Analysis Seminars mark the beginning of a new chapter in a series of online analysis seminars that started in September 2023, as an initiative of the Portuguese Group on Special Functions, Orthogonal Polynomials, and Applications, in collaboration with the University of Warsaw. These seminars have been characterized by the careful selection of their speakers.

Aiming to engage new audiences and expand the reach to a broader spectrum of researchers, the organizing committee was restructured in June 2025. The seminars are now coordinated by Kenier Castillo, one of the original founders of the series, from the University of Coimbra (Portugal), and Renato Álvarez-Nodarse, from the University of Seville (Spain). Previously, the seminars were organized in collaboration with Galina Filipuk (September 2023 - June 2025) and Dieudonné Mbouna (September 2023 - November 2024), both from the University of Warsaw (Poland).
