摘要：
Of concern is asymptotic stability for second order semilinear evolution equations in a Hilbert space with intermittent damping. We obtain asymptotic stability results, without the assumption that the damping coefficient a(t) is always positive, which means that the unique damping term could vanish sometimes. Moreover, we do not need the condition that the main linear operator A is coercive, that is, A could have a non-trivial kernel.
