A Course in the Calculus of Variations Optimization, Regularity, and Modeling

“The book is accessible to a wide audience, ranging from Ph.D. students to senior researchers. … This book, due to its breadth in covering many important topics in modern variational analysis, can serve as an excellent source of inspiration for a course on the calculus of variations, particularly one focused on applications.” (Pietro Celada, Mathematical Reviews, August, 2025) 

“I find this an extremely well-written textbook, which showcases many powerful notions and applications connected to the theory of calculus of variations. The author has definitely made an effort to collect and combine these selected topics in a natural and coherent way. I am convinced that this text will serve as a standard reference for the generations to come, embarking on a study of the analytic aspects of calculus of variations.” (Alpár R. Mészáros, zbMATH 1540.49001, 2024)
