Weakly compactly generated Frechet spaces [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1979
It is proved that a weakly compact generated Frechet space is Lindelöf in the weak topology. As a corollary it is proved that for a finite measure space every weakly measurable function into a weakly compactly generated Frechet space is weakly equivalent

The ideal of weakly compactly generated operators acting on a Banach space [PDF]

open access: yesJournal of Operator Theory, 2013
We call a bounded linear operator acting between Banach spaces weakly compactly generated ($\mathsf{WCG}$ for short) if its range is contained in a weakly compactly generated subspace of its codomain.

Observations on the Separable Quotient Problem for Banach Spaces

open access: yesAxioms, 2020
The longstanding Banach−Mazur separable quotient problem asks whether every infinite-dimensional Banach space has a quotient (Banach) space that is both infinite-dimensional and separable.

Eilenberg–Mac Lane Spaces for Topological Groups

open access: yesAxioms, 2019
In this paper, we establish a topological version of the notion of an Eilenberg−Mac Lane space. If X is a pointed topological space, π 1 ( X ) has a natural topology coming from the compact-open topology on the space of maps S

Quantum Field Theory on Spacetimes with a Compactly Generated Cauchy Horizon [PDF]

open access: yes, 1997
We prove two theorems which concern difficulties in the formulation of the quantum theory of a linear scalar field on a spacetime, (M,g_{ab}), with a compactly generated Cauchy horizon.

Quasi-free resolutions of Hilbert modules [PDF]

open access: yes, 2003
The notion of a quasi-free Hilbert module over a function algebra $\mathcal{A}$ consisting of holomorphic functions on a bounded domain $\Omega$ in complex $m$ space is introduced.

A local characterization of Kazhdan projections and applications [PDF]

open access: yes, 2018
We give a local characterization of the existence of Kazhdan projections for arbitary families of Banach space representations of a compactly generated locally compact group $G$.

Module categories for group algebras over commutative rings [PDF]

open access: yes, 2012
We develop a suitable version of the stable module category of a finite group G over an arbitrary commutative ring k. The purpose of the construction is to produce a compactly generated triangulated category whose compact objects are the finitely ...

Completely bounded bimodule maps and spectral synthesis [PDF]

open access: yes, 2017
We initiate the study of the completely bounded multipliers of the Haagerup tensor product $A(G)\otimes_{\rm h} A(G)$ of two copies of the Fourier algebra $A(G)$ of a locally compact group $G$. If $E$ is a closed subset of $G$ we let $E^{\sharp} = \{(s,t)

Smooth and polyhedral approximation in Banach spaces

open access: yes, 2015
We show that norms on certain Banach spaces $X$ can be approximated uniformly, and with arbitrary precision, on bounded subsets of $X$ by $C^{\infty}$ smooth norms and polyhedral norms.
