Simulation of perspective by nonlinear transformations

open access: yesMathematical Modelling and Analysis, 2013
A feature of the brain processing the visualization of objects is such that objects that are much farther away from the eye look smaller than closer objects to the eye.

Compactification of supermembranes [PDF]

open access: yesNuclear Physics B, 1999
We look at the vertical dimensional reduction of the supermembrane of M-theory to the D2-brane of Type IIA string theory. Our approach considers the soliton solutions of the two low energy field limits, D=11 and D=10 Type IIA supergravities, rather than the worldvolume actions. It is thus necessary to create a periodic array.

Quantifying completion

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2000
Approach uniformities were introduced in Lowen and Windels (1998) as the canonical generalization of both metric spaces and uniform spaces. This text presents in this new context of “quantitative” uniform spaces, a reflective completion theory which ...

A correspondence between proximity homomorphisms and certain frame maps via a comonad [PDF]

open access: yesCategories and General Algebraic Structures with Applications
We exhibit the proximity frames and proximity homomorphisms as a Kleisli category of a comonad whose underlying functor takes a proximity frame  to its frame of round ideals.

Bubble tree compactification of instanton moduli spaces [PDF]

open access: yes, 2021
We study the compactification of moduli spaces defined by the anti-self-dual (ASD) Yang-Mills equations on SU(2) or SO(3) bundles over closed oriented Riemannian 4-manifolds and 4-orbifolds.

Compactifications of convergens spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1979
This paper summarizes most of the results to date on convergence space compactifications, and establishes necessary and sufficient conditions for the existence of largest and smallest compactifications subject to various conditions imposed upon the ...

Some New Components of the Moduli Scheme MP3(2; -1; 2; 0) of Stable Coherent Torsion Free Sheaves of Rank 2 on P3

open access: yesМоделирование и анализ информационных систем, 2015
In this paper we consider Giseker-Maruyama moduli scheme M := MP3(2;¡1; 2; 0) of stable coherent torsion free sheaves of rank 2 with Chern classes c1 = -1, c2 = 2, c3 = 0 on 3-dimensional projective space P3.

Wonderful compactifications of Bruhat-Tits buildings [PDF]

open access: yesÉpijournal de Géométrie Algébrique, 2017
Given a split semisimple group over a local field, we consider the maximal Satake-Berkovich compactification of the corresponding Euclidean building. We prove that it can be equivariantly identified with the compactification which we get by embedding the

A NEW COMPACTIFICATION OF TEICHMÜLLER SPACE [PDF]

open access: yes
We construct a new compactification of Teichmüller space. We prove that this new compactification is finer than the Gardiner–Masur compactification of Teichmüller space and the action of the mapping class group on Teichmüller space extends continuously ...
