Shape theory and mathematical design of a general geometric kernel through regular stratified objects [PDF]

open access: yes, 2000
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This dissertation focuses on the mathematical design of a unified shape kernel for geometric computing, with possible applications to computer aided design (

Cellular structures in Topology [PDF]

open access: yes, 1990
This book describes the construction and the properties of CW-complexes. These spaces are important because firstly they are the correct framework for homotopy theory, and secondly most spaces that arise in pure mathematics are of this type.

Compactly Generated Domain Theory [PDF]

open access: yes, 2006
We propose compactly generated monotone convergence spaces as a well-behaved topological generalisation of directed-complete partial orders (dcpos). The category of such spaces enjoys the usual properties of categories of 'predomains' in denotational ...

On Asymmetric Distances

open access: yesAnalysis and Geometry in Metric Spaces, 2013
In this paper we discuss asymmetric length structures and asymmetric metric spaces. A length structure induces a (semi)distance function; by using the total variation formula, a (semi)distance function induces a length.

On functions between generalized topological spaces

open access: yesApplied General Topology, 2013
[EN] This paper investigates generalized topological spaces and functions between such spaces from the perspective of change of generalized topology. In particular, it considers the preservation of generalized connectedness properties by various classes of functions betweengeneralized topological spaces.

The weak topology on q-convex Banach function spaces

open access: yes, 2012
Let X(μ) be a Banach function space. In this paper we introduce two new geometric notions, q-convexity and weak q-convexity associated to a subset S of the unit ball of the dual of X(μ), 1 ≤ q < ∞.

On the completeness of total spaces of horizontally conformal submersions

open access: yesCommunications in Mathematics, 2021
In this paper, we address the completeness problem of certain classes of Riemannian metrics on vector bundles. We first establish a general result on the completeness of the total space of a vector bundle when the projection is a horizontally conformal ...

On Infinitesimal L_ω-smooth Functions.

open access: yesZanco Journal of Pure and Applied Sciences, 2022
The aim of this paper is to study smoothness, approximate continuity, and approximate derivative in a nonstandard manner with respect to infinitesimal parameters.

On automorphism groups of Toeplitz subshifts

open access: yesDiscrete Analysis, 2017
On automorphism groups of Toeplitz subshifts, Discrete Analysis 2017:11, 19 pp. A discrete dynamical system is a space $X$ with some kind of structure, together with a map $\sigma\colon X\to X$ that preserves the structure.

Two preservation results for countable products of sequential spaces [PDF]

open access: yes, 2007
We prove two results for the sequential topology on countable products of sequential topological spaces. First we show that a countable product of topological quotients yields a quotient map between the product spaces.
