Coverings of foliation algebras

open access: yes, 2017
This article is devoted to the geometric construction which states a natural correspondence between topological coverings of a foliated manifolds and noncommutative coverings of the operator algebras. However this correspondence is not one to one because there are noncommutaive coverings of foliations which do not comply with discussed in this article ...

Hirzebruch–Kummer covers of algebraic surfaces

open access: yesTURKISH JOURNAL OF MATHEMATICS, 2019
The aim of this paper is to show that using some natural curve arrangements in algebraic surfaces and Hirzebruch-Kummer covers one cannot construct new examples of ball-quotients, i.e., minimal smooth complex projective surfaces of general type satisfying equality in the Bogomolov-Miyaoka-Yau inequality.

A unified approach of catastrophic events [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2004
Although there is an accumulated charge of theoretical, computational, and numerical work, like catastrophe theory, bifurcation theory, stochastic and deterministic chaos theory, there is an important feeling that these matters do not completely cover ...
