| 題目 | Energy decay for a nonlinear Generalized Klein-Gordon equation in exterior domains with a localized nonlinear dissipative term |
| 概要 | We give a certain energy decay rate for solutions of the exterior initial-boundary value problem of the nonlinear wave equations. We call our equation as a nonlinear generalized Klein-Gordon equation since the term $g(u)$ plays an essential role in our argument. Note that concerning energy decay, no result is known when both of $\rho(x,u_t)$ and $g(u)$ are nonlinear.
