Discrete Variational Problems with Interfaces

Roberto Alicandro is Full Professor at the University of Naples. He works in the calculus of variations and homogenization. His results have applications in different fields, including atomistic-to-continuum limits for nonlinear models in materials science, topological singularities and defects in materials. He co-authored the monograph 'A Variational Theory of Convolution-type Functionals' (2022). Andrea Braides is Full Professor at SISSA (International School for Advanced Studies), Trieste. He was an Invited Speaker at the 2014 International Congress of Mathematicians and received the Levi-Civita prize in 2015. He is the author of five books including 'Gamma-convergence for Beginners' (2002 ), 'Local Minimization, Variational Evolution and Gamma-convergence' (2014) and 'Geometric Flows on Planar Lattices' (2021). Marco Cicalese is Professor of Mathematical Continuum Mechanics at the Technical University of Munich. He works in the calculus of variations and its applications to materials science. Margherita Solci is Associate Professor at the University of Sassari, Italy. She works in the calculus of variations, especially in the passage discrete-to-continuum, on which she has co-authored the monograph 'Geometric Flows on Planar Lattices' (2021). She has directed several projects on mathematical modeling applied to cultural heritage, editing two volumes on this theme.
