I am proud to announce that a book I have written is out. The book is entitled Theory of hyperconvex metric spaces: a beginner’s guide. Hyperconvex spaces are a very interesting (though a bit abstract) topic between mathematical analysis and topology. They have remarkable properties; the book is mainly devoted to their connections with fixed point theory.
The book is published by the Juliusz P. Schauder Center for Nonlinear Studies in the series Lecture Notes in Nonlinear Analysis.
