Asymptotic profile of solutions for strongly damped Klein‐Gordon equations
Asymptotic profile of solutions for strongly damped Klein‐Gordon equations
We consider the Cauchy problem in R n for strongly damped Klein‐Gordon equations. We derive asymptotic profiles of solutions with weighted L 1,1 ( R n ) initial data by a simple method introduced by the second author. Furthermore, from the obtained asymptotic profile, we get the optimal decay order …
