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 (September 2023-July 2025) and Dieudonné Mbouna
(September 2023-December 2024) from the University of
Warsaw (Poland).
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.
