✦ Synopsis

In this paper (8, Z, p) will always denote a finite measure space and X a BA-NACH space. K ( p , 9) will denote the BANACH space of p-continuous X-valued measures G defined on L ? having relatively coinpact range, endowed with the semivariation norm (see

Purpose of this note is to show that if X is a BANACH space having weak* sequentially compact dual balls or a separably complemented BANACH space, then K ( p , X ) has the socalled GELFAND-PHILLIPS property (or R ( p , X ) is a GELFAWD-PHILLIPS space), i.e. any limited set in K ( p , X ) is a relatively compact set; we recall that a (bounded) set A in a BANACR space E is said to be limited if for any (x:) c E*, x,* -%, we have lim sup Is,*(x)l= 0. to* n z c A This class of BAWACH spaces has been recently investigated by BOURGAIN

In order to obtain the results above mentioned, we have to use some lemmas.

A closed nonvoid subset Z of a Banach space X is called antiproximinal if no point outside Z has a nearest point in Z. The aim of the present paper is to prove that, for a compact Hausdorff space T and a real Banach space E, the Banach space C T E , of all continuous functions defined on T and with

## Introduction. The theory of discrete approximation serves as a framework of approximation and discretization methods for the numerical solution of functional equations. This theory allows a unified functional-analytic treatment of these methods. It was developed by several authors (see e.g. the

This paper investigates periodic boundary value problems for a class of secondorder nonlinear impulsive integro-differential equations of mixed type in a Banach space. By establishing a comparison result, criteria on the existence of maximal and minimal solutions are obtained.
