An essay on noncommutative topology

open access: yesTopology and Its Applications, 1989
By ``noncommutative topology'' the authors mean \textit{C. J. Mulvey}'s theory of quantales [Rend. Circ. Mat. Palermo., II. Ser., Suppl. 12, 99- 104 (1986; Zbl 0633.46065)]. This was originally introduced in the hope of providing a ``Gelfand-type'' representation for noncommutative \(C^*\)-algebras.

Noncommutative Koszul algebras from combinatorial topology [PDF]

open access: yesJournal Fur Die Reine Und Angewandte Mathematik, 2010
Associated to any uniform finite layered graph Gamma there is a noncommutative graded quadratic algebra A(Gamma) given by a construction due to Gelfand, Retakh, Serconek and Wilson. It is natural to ask when these algebras are Koszul. Unfortunately, a mistake in the literature states that all such algebras are Koszul.

Noncommutative Topologies, Localization, and Sheaves

Communications in Algebra, 2008
In this note, we introduce and study the notion of sheaf on a noncommutative topology and construct an associated sheafification functor in this noncommutative context. It appears that abstract localization in the category of presheaves on a partially ordered set provides an elegant way to define this sheafification functor, generalizing similar ...

Noncommutative Topology: Spaces

2001
The geometrical study of quadratic curves or surfaces, i.e., zero sets of second-degree polynomials, proceeds by examining points of intersection or tangent lines directly; but already for cubic curves it pays to examine first the ideal of all polynomials that vanish on the curve: in this way the study of an algebraic variety (the zero set of a given ...

Noncommutative geometry, topology, and the standard model vacuum [PDF]

open access: yesJournal of Mathematical Physics, 2006
As a ramification of a motivational discussion for previous joint work, in which equations of motion for the finite spectral action of the standard model were derived, we provide a new analysis of the results of the calculations therein, switching from the perspective of spectral triple to that of Fredholm module and thus from the analogy with ...
