Iberian Online Analysis Seminars
The Iberian Online Analysis Seminars mark
the beginning of a new chapter in a series of online
analysis seminars that commenced in September 2023, as an
initiative of the Portuguese Group on Special Functions,
Orthogonal Polynomials, and Applications, in collaboration
with the University of Warsaw. Aiming to embrace new
audiences and engage a broader spectrum of researchers,
the organizing committee has been restructured as of
September 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 - July2025), from the University of Warsaw (Poland), and Dieudonne Mbouna (September 2023 - November 2024).
