##### Description

This project stems out from the collaboration of various people of the units that in recent years developed new ideas, techniques and methods in the study of geometric evolution problems, variational problems of isoperimetric type and shape optimization problems. The common background of all participants involved in this project led in a natural way to the formation of our research units and to the formulation of the present research program, divided in three main themes: geometric evolution problems and curvature flows of network, capillarity problems and isoperimetric inequalities, shape optimization. All these topics are strictly intertwined and share a large amount of techniques coming from Calculus of Variations, the Regularity theory of PDEs and Geometric Measure Theory. Moreover, apart from their intrinsic mathematical interest, some of the problems we intend to study originate from well known models developed in the fields of Materials Science and Structural Engineering.
