Kadec Norms on Spaces of Continuous Functions [PDF]

open access: yes, 2006
2000 Mathematics Subject Classification: Primary: 46B03, 46B26. Secondary: 46E15, 54C35.We study the existence of pointwise Kadec renormings for Banach spaces of the form C(K).

Rational homotopy of mapping spaces between complex Grassmannians

open access: yes, 2020
The complex Grassmann Gr(k, n) is the space of k dimensional subspaces of Cn. It is a complex manifold of complex dimension k(n − k). There is a natural inclusion ik,n : Gr(k, n) ,→ Gr(k, n + r).

On τ−covers using ideals and some of its consequences

open access: yes, 2019
In this paper we primarily introduce an ideal version of τ-covers studied in [18, 19]. We establish the inter-relationships between I-τ-covers and I-γ , I-large [3, 5] and κ-covers[2, 7].

Exponential law and theta-continuous functions

open access: yes, 1985
The category θ-Top of topological spaces and θ-continuous functions is not Cartesian closed; but it is known that under certain local property assumptions, the exponential law in θ-Top is fulfilled.

Precompactness And Compactness In The Natural Function Spaces Of The Category Of Semiuniform Convergence Spaces

open access: yes, 1997
. Semiuniform convergence spaces form a common generalization of (symmetric) limit spaces (and thus of symmetric topological spaces) as well as of uniform limit spaces (and thus of uniform spaces) with many convenient properties such as cartesian ...

Function Algebras And The Lattice Of Compactifications

open access: yes, 2007
. We provide some conditions as to when K(X) ¸ = K(Y ) for two locally compact spaces X and Y (where K(X) is the lattice of all Hausdorff compactifications of X). More specifically, we prove that K(X) ¸ = K(Y ) if and only if C (X)=C 0 (X) ¸ = C

Two point-picking games derived from a property of function spaces

open access: yes, 2018
We present a study of two versions of the point-picking game defined by Berner and Juhasz. Given a space X there are two rivals O and P who take turns playing on X. In the n-th round Player O takes a non-empty open subset Un of the space X and P responds

open access: yes, 2010
The authors consider for a bounded subset H of a Banach space E the De Blasi measure of weak noncompactness w(H) and the measure of weak noncompactness g(H) based on Grothendieck’s double limit criterion.
