A note on strong instability of standing waves for some semilinear wave and heat equations

Abstract

The initial value problems for some semilinear wave and heat equations are investigated in two space dimensions. By proving the existence of ground state, strong instability of standing waves for the associated wave and heat equations are obtained.
