On the energy decay estimate for the dissipative wave equation with very fast oscillating coefficient and smooth initial data
Kazunori Goto, Fumihiko Hirosawa
In this paper we consider energy decay estimates for the Cauchy problems of dissipative wave equations with time dependent coefficients, in particular, the coefficients consisting…

On the wave-like energy estimates of Klein-Gordon type equations with time dependent potential
Kazunori Goto, Fumihiko Hirosawa
We consider the conditions for the time dependent potential in which the energy of the Cauchy problem of Klein-Gordon type equation asymptotically behaves like the energy of the wa…
