This talk explores a series of preservation principles concerning well-orders and well quasi-orders, wqo. Well-orders are foundational in mathematical logic, playing a central role in set theory—espec...
We present a construction which associates to differential equations discrete groups. In order to establish this relation we use automata and random walks on ultra discrete limits. We discuss related ...
Presentazione del libro "La geometria non euclidea. Una breve storia dall'antichità a Poincaré" di Alberto CogliatiIntervengono Paolo Freguglia ed Enrico RogoraIn collaborazione con l'Associazione "Am...
A codimension one foliation of a 3-manifold is a partition of the manifold by immersed surfaces which locally pile up nicely like parallel affine planes but which can have a very complicated global be...
The talk concerns a phase field approximation for sharp interface energies, defined on partitions, as appropriate for modeling grain boundaries in polycrystals. The label takes value in O(d)/G, where ...
We consider the spectral problem for the stationary Maxwell's equations under homogeneous boundary conditions in a cavity, and we investigate how the eigenvalues depend on perturbations of the cavity'...
The inverse spectral problem asks to what extent one can recover the geometry of a manifold from knowledge of either its Laplace spectrum or dynamical counterparts, e.g., the (marked) length spectrum....
Il seminario sarà diviso in due parti quasi indipendenti. Nella prima parte parleremo di calcolo parallelo, delle differenze tra CPU (central processing unit) e GPU (graphics processing unit) e in par...
