Portuguese-Polish Online Analysis Seminars

The Iberian Online Analysis Seminars signify the dawn of a new chapter in a series that began as a collaborative endeavor between the Portuguese Group on Special Functions, Orthogonal Polynomials, and Applications and the University of Warsaw. Initially conceived under the name Portuguese-Polish Online Analysis Seminars, this initiative was organized by Kenier Castillo from the University of Coimbra (Portugal), and Galina Filipuk and Dieudonné Mbouna from the University of Warsaw (Poland). Over the course of nearly two years, these seminars have cultivated a distinctive identity, blending a fresh perspective with an expansive vision that has brought together distinguished speakers and fostered meaningful dialogue in the mathematical community.

The seminars now aspire to extend their reach, embracing new audiences and engaging with a broader spectrum of researchers. In pursuit of this objective, and in recognition of the evolving nature of the project, the seminars will, from September onwards, adopt the new title Iberian Online Analysis Seminars. From that point forward, the seminars will be organized by Kenier Castillo and Renato Álvarez-Nodarse from the University of Seville (Spain), ensuring continuity and the continued growth of this vibrant intellectual enterprise.
