A convex subset X of a locally convex linear topological space is said to have a Kakutani-type fixed point property if every Kakutani-type multivalued mapping from X to X has a

We determine the sets B which have the property of being invariant under projections onto lines through 0 subject to a weak boundedness type requirement. Keywords: convex,

A subset A of a space X is called an S-set in X [7] if every cover of A by regular closed subsets of X has a finite subcover, and called an rc-Lindel¨of set in X (resp., an almost

Proof: Assume by contradiction that there exist a compact Hausdorff semi radial space X and a compact Hausdorff pseudo radial space Y such that the product Z = X × Y is not

More recently it was shown by one of the authors ([6]) that the pointwise closure of I(X, d) is locally compact if the space Σ(X) of the connected components of X is

Abstract: We investigate the role that weak forms of the axiom of choice play in countable Tychonoff products, as well as countable disjoint unions, of Loeb and selective metric

It is well-known that S-metrizable spaces are locally connected and that if 0 is a Property S metric for X, then the usual metric completion (,) of (X,0) is a compact,

Since the deformation lemma is also true with Cerami condition, we can assume that ϕ satisfies the Cerami condition instead of the Palais-Smale condition.. However, in the
