Moment conditions and lower bounds in expanding solutions of wave equations with double damping terms
Ryo Ikehata, Hironori Michihisa
In this report we obtain higher order asymptotic expansions of solutions to wave equations with frictional and viscoelastic damping terms. Although the diffusion phenomena are domi…

Asymptotic profile of solutions for strongly damped Klein-Gordon equations
Ryo Ikehata
We consider the Cauchy problem in the whole space for strongly damped Klein-Gordon equations. We derive asymptotic profles of solutions with weighted initial data by a simple metho…
