Generalized convolution quadrature based on the trapezoidal rule
Lehel Banjai, Matteo Ferrari
We present a novel generalized convolution quadrature method that accurately approximates convolution integrals. During the late 1980s, Lubich introduced convolution quadrature tec…

A virtual element method for the solution of 2D time-harmonic elastic wave equations via scalar potentials
Silvia Falletta, Matteo Ferrari, Letizia Scuderi
In this paper, we propose and analyse a numerical method to solve 2D Dirichlet time-harmonic elastic wave equations. The procedure is based on the decoupling of the elastic vector…
