“…The Gelfand-Phillips property has attracted considerable attention over the last twenty years, which resulted in several interesting papers, see for instance Bourgain & Diestel [5], Drewnowski [6], Schlumprecht [28], Sinha & Arora [26], Freedman [9]. The class (GP) of spaces having this property is quite wide, and includes (i) l 1 (κ) for every κ;…”
We answer in negative the problem if the existence of a Pmeasure implies the existence of a P-point. Namely, we show that if we add random reals to a certain 'unique P-point' model, then in the resulting model we will have a P-measure but not P-points. Also, we investigate the question if there is a P-measure in the Silver model. We show that rapid filters cannot be extended to a P-measure in the extension by ω product of Silver forcings and that in the model obtained by the countable support ω 2 -iteration of countable product of Silver forcings there are no P-measures of countable Maharam type.
“…Hence separable or reflexive Banach spaces are Gelfand-Phillips spaces. (See also [7] and [17].) Of course, their intrinsic properties have also been studied (see e.g.…”

Abstract. We prove that scalar-valued polynomials are weakly continuous on limited sets and that, as in the case of linear mappings, every c 0 -valued polynomial maps limited sets into relatively compact ones. We also show that a scalar-valued polynomial whose derivative is limited is weakly sequentially continuous.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
