Versatile asymmetrical tight extensions

Olivier Olela Otafudu, Zechariah Mushaandja (2017)

Topological Algebra and its Applications

Similarity:

We show that the image of a q-hyperconvex quasi-metric space under a retraction is q-hyperconvex. Furthermore, we establish that quasi-tightness and quasi-essentiality of an extension of a T0-quasi-metric space are equivalent.

On Quasi-Normality of Two-Sided Multiplication

Amouch, M. (2009)

Serdica Mathematical Journal

Similarity:

2000 Mathematics Subject Classification: 47B47, 47B10, 47A30. In this note, we characterize quasi-normality of two-sided multiplication, restricted to a norm ideal and we extend this result, to an important class which contains all quasi-normal operators. Also we give some applications of this result.

The quasi topology associated with a countably subadditive set function

Bent Fuglede (1971)

Annales de l'institut Fourier

Similarity:

This is a general study of an increasing, countably subadditive set function, called a capacity, and defined on the subsets of a topological space X . The principal aim is the study of the “quasi-topological” properties of subsets of X , or of numerical functions on X , with respect to such a capacity C . Analogues are obtained to various important properties of the fine topology in potential theory, notably the quasi Lindelöf principle (Doob), the existence of a fine support (Getoor), and...
