Learning collision operators from plasma phase space data using differentiable simulators
Diogo D. Carvalho, Pablo J. Bilbao, Warren B. Mori +2
We propose a methodology to infer collision operators from phase space data of plasma dynamics. Our approach combines a differentiable kinetic simulator, whose core component in th…

Scattering theory for difference equations with operator coefficients
David Sher, Luis Silva, Boris Vertman +1
We consider a second order difference equation with operator-valued coefficients. More precisely, we study either compact or trace class perturbations of the discrete Laplacian in…

Spectral analysis of infinite Marchenko-Slavin matrices
Sergio Palafox, Luis O. Silva
This work tackles the problem of spectral characterization of a class of infinite matrices arising from the modelling of small oscillations in a system of interacting particles. Th…
