Exponential integrators for second-order in time partial differential equations

D Phan, A Ostermann - Journal of Scientific Computing, 2022 - Springer
Two types of second-order in time partial differential equations, namely semilinear wave
equations and semilinear beam equations are considered. To solve these equations with …

Double diffusion structure of logarithmically damped wave equations with a small parameter

A Piske, RC Charão, R Ikehata - Journal of Differential Equations, 2022 - Elsevier
We consider a wave equation with a nonlocal logarithmic dam** depending on a small
