Nel corso della giornata sono stati affrontati temi diversi: dalla Contrattazione centralizzata CRUI-CARE all’Open Access, dai servizi Nilde al costo degli abbonamenti. Nel pomeriggio una t...
Abstract: We present a proof that a system of NN fermions interacting with an additional particle via point interactions is stable if the ratio of the mass of the additional particle to the one of the...
Abstract: We prove uniqueness in inverse acoustic scattering in the case the density of the medium has an unbounded gradient across Σ⊂ΩΣ⊂Ω, where ΩΩ is a 3D-Lipschitz domain. The corresponding direct ...
Abstract: We consider a way of defining quantum Hamiltonians involving particle creation and annihilation based on an interior-boundary condition (IBC) on the wave function, where the wave function is...
Abstract: I will present a way to derive, via hydrodynamic limits, weak solutions to the 1D isothermal Euler equations in Lagrangian coordinates. This is obtained from a microscopic anharmonic chain w...
Abstract: We introduce a gradient flow formulation of linear Boltzmann equations. Under a diffusive scaling we derive a diffusion equation by using the machinery of gradient flows. This is a joint wor...
Abstract: The "Weyl fermion" was discovered in a topological semimetal in 2015. Its mathematical characterisation turns out to involve deep and subtle results in differential topology. I will outline ...
