Abstract

We consider abstract second order evolution equations with unboundedfeedback with delay. Existence results are obtained under somerealistic assumptions. Sufficient and explicit conditions are derived that guarantee the exponential or polynomial stability. Some new examples that enter into our abstract framework are presented.
