Relations between principal eigenvalue and torsional rigidity with Robin boundary conditions
Giuseppe Buttazzo, Simone Cito, Francesco Solombrino
We consider the torsional rigidity and the principal eigenvalue related to the Laplace operator with Dirichlet and Robin boundary conditions. The goal is to find upper and lower bo…

From discrete to continuum in the helical XY-model: emergence of chirality transitions in the to limit
Marco Cicalese, Dario Reggiani, Francesco Solombrino
We analyze the discrete-to-continuum limit of a frustrated ferromagnetic/anti-ferromagnetic -valued spin system on the lattice as . For…

Korn and Poincaré-Korn inequalities: A different perspective
Giovanni Di Fratta, Francesco Solombrino
We present a concise point of view on the first and the second Korn's inequality for general exponent and for a class of domains that includes Lipschitz domains. Our argument i…
