Measure of noncompactness

The paper deals with the unit sphere S∞ of a Hilbert space endowed with natural spherical metric. In the paper, we give a geometric characterization of extremal sets contained in a hemi-sphere of S∞ that generalizes previously known results with respect to the classical Jung theorem.

Based on our previous result and by using the technique on α-minimal and X-minimal sets with respect to the Kuratowski and Hausdorff measures of noncompactness, we give some new geometric characterizations of extremal sets in Hilbert spaces.

A control system governed by semilinear fractional differential inclusions with infinite delays is studied. We prove the stabilizability in a weak sense for mentioned system under the assumption that its linear part is strongly stabilizable.

In this paper, we will prove some fixed point theorems for the sum and the product of nonlinear weakly sequentially continuous operators acting on a WC–Banach algebra. Our results improve and correct some recent results given by Banas and Taoudi, and extend several earlier works using the condition (P).

This paper is concerned with the existence of global mild solutions and positive mild solutions to initial value problem for a class of mixed type semilinear evolution equations with noncompact semigroup in Banach spaces. The main method is based on a new fixed point theorem with respect to convex-power condensing operator.
