Almost periodic solution of a class of semilinear wave equations with boundary dissipation
The author studies time almost periodic solutions to the equation \[ u_{tt}-u_{xx}=f(t,x,u,u_t,u_x) \] (\(x\in (0,1)\)) with the following boundary conditions \[ u(t,0)=0,\;u_x(t,1)+\lambda u_t(t,1)=0 \] where \(\lambda >0\).
