In Section 3, we show that the clique- width is unbounded in any superfactorial class of graphs, and in Section 4, we prove that the clique-width is bounded in any hereditary

To study the existence of a global attractor, we have to find a closed metric space and prove that there exists a global attractor in the closed metric space. Since the total mass

In this paper, under some conditions, we show that the so- lution of a semidiscrete form of a nonlocal parabolic problem quenches in a finite time and estimate its semidiscrete

Wall theorems give local lower bounds for the p-measure of the boundary of a domain in the euclidean n -space.. We improve earlier results by replacing the euclidean metric by the

[11] A locally symmetric contact metric space is either Sasakian and of constant curvature 1, or locally isometric to the unit tangent sphere bundle of a Euclidean space with

We will give a different proof of a slightly weaker result, and then prove Theorem 7.3 below, which sharpens both results considerably; in both cases f denotes the canonical

The purpose of this paper is to apply a new method, based on the envelope theory of the family of planes, to derive necessary and sufficient conditions for the partial
