Robust H(curl)-based finite element methods for the incompressible MHD system

Lourenço Beirão da Veiga, Sergio Gómez, Ilaria Perugia +1

We propose and analyze a class of finite element methods for the time-dependent incompressible magnetohydrodynamics system based on -conforming discretizations fo…

Surrogate modeling of resonant behavior in scattering problems through adaptive rational approximation and sketching

Davide Pradovera, Ralf Hiptmair, Ilaria Perugia

This paper describes novel algorithms for the identification of (almost-)resonant behavior in scattering problems. Our methods, relying on rational approximation, aim at building s…

On polynomial Trefftz spaces for the linear time-dependent Schrödinger equation

Sergio Gómez, Andrea Moiola, Ilaria Perugia +1

We study the approximation properties of complex-valued polynomial Trefftz spaces for the -dimensional linear time-dependent Schrödinger equation. More precisely, we prove t…

Design and performance of a space-time virtual element method for the heat equation on prismatic meshes

Sergio Gómez, Lorenzo Mascotto, Ilaria Perugia

We present a space-time virtual element method for the discretization of the heat equation, which is defined on general prismatic meshes and variable degrees of accuracy. Strategie…

Exponential Convergence of -Time-Stepping in Space-Time Discretizations of Parabolic PDEs

Ilaria Perugia, Christoph Schwab, Marco Zank

For linear parabolic initial-boundary value problems with self-adjoint, time-homogeneous elliptic spatial operator in divergence form with Lipschitz-continuous coefficients, and fo…
