Inequalities and compactness

Abstract

We use the inequalities of Holder, Gronwall and Wirtinger type to establish sufficient conditions for that the null function is the unique nonnegative solution of some integral inequalities. Such conditions are useful to guarantee compactness properties of Monch and Palais-Smale type for integral operators on spaces of vector-valued functions. An applications to superlinear boundary value problems in Hilbert spaces is also presented.
