Assume that Au = f (1) is a solvable linear equation in a Hilbert space H, A is a linear, closed, densely defined, unbounded operator in H, which is not boundedly invertible, so p...
The main goal of this article is to discuss a controllability approach to the image matching / shape identification problem, an important issue in many applications, medical ones ...
The present work is concerned with the uniqueness problem of best simultaneous approximation. An n-dimensional l1- or l-simultaneous unicity space is characterized in terms of Pro...
Let G = (V, E) be a simple graph. A set D V is a dominating set of G if every vertex of V - D is adjacent to a vertex of D. The domination number of G, denoted by (G), is the min...

We provide a complete answer to the problem which consists in finding an unpointed convex cone lying at minimal bounded Pompeiu-Hausdorff distance from a pointed one. We give also...
By a combination of asymptotic ODE estimates and numerical Evans function calculations, we establish stability of viscous shock solutions of the isentropic compressible Navier
