WEAK INJECTIVE AND WEAK FLAT COMPLEXES

Glasgow Mathematical Journal, 2015
AbstractLet R be an arbitrary ring. We introduce and study a generalization of injective and flat complexes of modules, called weak injective and weak flat complexes of modules respectively. We show that a complex C is weak injective (resp. weak flat) if and only if C is exact and all cycles of C are weak injective (resp. weak flat) as R-modules.

Weak Galois and Weak Cocleft Coextensions

Algebra Colloquium, 2007
For a weak entwining structure (A, C, ψ) living in a braided monoidal category with equalizers and coequalizers, we formulate the notion of weak A-Galois coextension with normal basis and we show that these Galois coextensions are equivalent to the weak A-cocleft coextensions introduced by the authors.

Weak and Weak* Topologies

2009
In this chapter, we will study topologies on Banach spaces which are weaker (i.e. coarser) than the norm topology.

The Weak and Weak Topologies

1998
The topology induced by a norm on a vector space is a very strong topology in the sense that it has many open sets. This has some advantages, especially since a function whose domain is such a space finds it particularly easy to be continuous, but it also has its disadvantages.

Flatness Is Not a Weakness

2000
We propose an extension, called Lp+, of the temporal logic LTL, which enables talking about finitely many register values: the models are infinite words over tuples of integers (resp. real numbers). The formulas of Lp+ are flat: on the left of an until, only atomic formulas or LTL formulas are allowed.

The Weak and Weak* Topologies: An Introduction

1984
As we saw in our brief study of compactness in normed linear spaces, the norm topology is too strong to allow any widely applicable subsequential extraction principles. Indeed, in order that each bounded sequence in X have a norm convergent subsequence, it is necessary and sufficient that X be finite dimensional.
