Finite Dimensional Chebyshev Subspaces of Lo

open access: yesSultan Qaboos University Journal for Science, 2017
If A is a subset of the normed linear space X, then A is said to be proximinal in X if for each xÎX there is a point y0ÎA such that the distance between x and A; d(x, A) = inf{||x-y||: yÎA}= ||x­-y0||.

Reflexivity in Banach lattices and their subspaces

open access: yesJournal of Functional Analysis, 1972
AbstractThe present paper studies in detail necessary and sufficient conditions for a subspace of a Banach Lattice to be weakly complete, weakly compact or reflexive.The results are wholly similar to those obtained for subspaces of Banach spaces with unconditional bases.

Nonvanishing Preservers and Compact Weighted Composition Operators between Spaces of Lipschitz Functions

open access: yesAbstract and Applied Analysis, 2013
We will give the -Lipschitz version of the Banach-Stone type theorems for lattice-valued -Lipschitz functions on some metric spaces. In particular, when and are bounded metric spaces, if is a nonvanishing preserver, then is a weighted composition ...

Spaces generated by the cone of sublinear operators

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2018
This paper deals with a study on classes of non linear operators. Let $SL(X,Y)$ be the set of all sublinear operators between two Riesz spaces $X$ and $Y$. It is a convex cone of the space $H(X,Y)$ of all positively homogeneous operators.
