Pseudospectral roaming contour integral methods for convection-diffusion equations
Nicola Guglielmi, Maria López-Fernández, Mattia Manucci
We generalize ideas in the recent literature and develop new ones in order to propose a general class of contour integral methods for linear convection-diffusion PDEs and in partic…

Sparse data-driven quadrature rules via -quasi-norm minimization
Mattia Manucci, Jose Vicente Aguado, Domenico Borzacchiello
In this paper we show the use of the focal underdetermined system solver to recover sparse empirical quadrature rules for parametrized integrals from existing data, consisting of t…
