Foreword
The present Number 2 of Volume 28 (2021) of the Journal of Convex Analysis is dedicated to Umberto Mosco on the occasion of his 80th birthday. The name of Umberto Mosco is a key name in the field of variational analysis and the list of his contributions ranges over several topics in convex analysis, calculus of variations, partial differential equations, optimization problems, analysis on fractal domains.
The impact of his scientific work, in particular his seminal papers on the convergence of convex sets and functions, has been truly remarkable. His contributions opened indeed several new directions of research and the students he trained to research are continuing to develop his brilliant pioneering ideas.
The content of this number of the journal consists of 22 articles, mostly related to the fields where Umberto Mosco had major contributions. The Editors and the Publisher of the Journal of Convex Analysis warmly thank all the authors who contributed to the present issue and all the referees for their review works.
