New Frontiers in Homogenization and Fractional Calculus (Trends in Mathematics)

This volume is based on the talks presented at the "New Frontiers in Homogenization and Fractional Calculus" conference, held at CRM-Barcelona on March 24-25, 2025.This event was organized to celebrate the 50th anniversary of the mathematical technique of Gamma-convergence, introduced by Ennio De Giorgi and Tullio Franzoni in 1975. Originally developed for applied purposes, this technique remains a fundamental tool in the study of various scientific phenomena, such as homogenization, phase transitions, and the asymptotic analysis of partial differential equations. At the same time, there has been a growing interest in the study of nonlocal problems, particularly due to their relevance in probability theory.In addition to representing a particularly challenging area of mathematics, these problems have become increasingly relevant in material science applications. The contributions in this volume cover a wide range of topics and reflect the main areas of current research in variational c
