Jerzy Kąkol is Full Professor of Mathematics at the Adam Mickiewicz University of Poznań (Poland). His research is strongly connected with functional analysis, infinite-dimensional and descriptive topology, and applications of topological methods in functional analysis. He published over 180 research papers, mainly in functional analysis and (descriptive) topology. In 1989/91 he was a scholarship holder of the Alexander von Humboldt foundation, which he carried out at the Universities of Munich and Saarbrucken. He conducted scientific research as a visiting professor at several universities in US (New York, Gainesville and Grand Forks, among others) and in Spain (Valencia, Murcia). Since 2005 he has been a member of the Spanish Royal Academy of Sciences. Wieslaw Kubiś is Full Professor of Mathematics, currently a Researcher in the Czech Academy of Sciences, Prague, Czechia, and also Professor at the Cardinal Stefan Wyszynski University in Warsaw, Poland. His research spans several areas of pure mathematics: set theory, category theory, topology, and functional analysis---aiming at developing generic mathematical structures. He has published over 60 research articles, and is a co-author of the first edition of the current monograph. Prof. Kubiś is currently leading a prestigious five-year Excellence in Basic Research Grant Project EXPRO, awarded by the Czech Science Foundation. Manuel López-Pellicer was Full Professor of Mathematics at the Polytechnic University of Valencia (Spain) until 2015 and since then he is Professor Emeritus. His research is mainly connected with Functional Analysis, General Topology and applications of topological methods in functional analysis, with over 120 publications. He is a coauthor of the monographs ""Metrizable barrelled spaces"" (Longman 1995) and of the first edition of the current monograph ""Descriptive Topology in Selected Topics of Functional Analysis"" (Springer 2011). Since 1998 he is a member of the Royal Academy of Sciences of Spain, being since 2004 editor-in-chief of its Mathematical Journal, with acronym name RACSAM. Damian Sobota is a senior postdoc researcher at the Kurt Gödel Research Center for Mathematical Logic at the University of Vienna, where he has worked since finishing his PhD thesis at the Institute of Mathematics of the Polish Academy of Sciences in 2016. His research interests mostly concern applications of forcing and infinitary combinatorics to problems arising in Banach space theory and measure theory. He is an author or co-author of over 20 research papers.
