On topological groups with remainder of character k
Applied General Topology, 2016 In [A.V. Arhangel'skii and J. van Mill, On topological groups with a first-countable remainder, Top. Proc. 42 (2013), 157-163] it is proved that the character of a non-locally compact topological group with a first countable remainder doesn't exceed ...

(0,2) string compactifications [PDF]
Nuclear Physics B - Proceedings Supplements, 1997 Using the simple current method we study a class of $(0,2)$ SCFTs which we conjecture to be equivalent to (0,2) sigma models constructed in the framework of gauged linear sigma models.

Reviews of Modern Physics, 2007 We review recent work in which compactifications of string and M theory are constructed in which all scalar fields (moduli) are massive, and supersymmetry is broken with a small positive cosmological constant, features needed to reproduce real world physics.

Simulation of perspective by nonlinear transformations
Mathematical 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.

International Journal of Mathematics and Mathematical Sciences, 1981 The relationships between a convergence space and its star compactification is studied. Special attention is given to lifting properties of this compactification.

International 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]
Categories and General Algebraic Structures with ApplicationsWe 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.

Compactification of closed preordered spaces
Applied General Topology, 2012 A topological preordered space admits a Hausdorff T2-preorder compactification if and only if it is Tychonoff and the preorder is represented by the family of continuous isotone functions.

Compactifications of convergens spaces
International 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 ...

Моделирование 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.
