, 1997 Noncommutative Spaces It was noticed a long time ago that various properties of sets of points can be restated in terms of properties of certain commutative rings of functions over those sets.

Noncommutative Symmetries and Gravity [PDF]
, 2006 Spacetime geometry is twisted (deformed) into noncommutative spacetime geometry, where functions and tensors are now star-multiplied. Consistently, spacetime diffeomorhisms are twisted into noncommutative diffeomorphisms.

Zitterbewegung in noncommutative geometry [PDF]
International Journal of Modern Physics A, 2019 We have considered the effects of space and momentum noncommutativity separately on the zitterbewegung (ZBW) phenomenon. In the space noncommutativity scenario, it has been expressed that, due to the conservation of momentum, the Fourier decomposition of the expectation value of position does not change.

Spectral Noncommutative Geometry Standard Model and all that [PDF]
International Journal of Modern Physics A, 2019 We review the approach to the Standard Model of particle interactions based on spectral noncommutative geometry. The paper is (nearly) self-contained and presents both the mathematical and phenomenological aspects.

NONCOMMUTATIVE GEOMETRIES: AN OVERVIEW [PDF]
International Journal of Modern Physics A, 2008 I make a very introductory overview of noncommutative geometries, focusing on the DFR model for Minkowski space; in this model the noncommutativity, or “fuzziness”, of spacetime events emerges at semiclassical level putting together the Heisenberg principle with general relativity.

On the Koszul formula in noncommutative geometry [PDF]
Reviews in Mathematical Physics, 2019 We prove a Koszul formula for the Levi-Civita connection for any pseudo-Riemannian bilinear metric on a class of centered bimodule of noncommutative one-forms. As an application to the Koszul formula, we show that our Levi-Civita connection is a bimodule

Particle Physics from Almost Commutative Spacetimes [PDF]
, 2012 Our aim in this review article is to present the applications of Connes' noncommutative geometry to elementary particle physics. Whereas the existing literature is mostly focused on a mathematical audience, in this article we introduce the ideas and ...

On the Noncommutative Geometry of Tilings [PDF]
, 2015 This is a chapter in an incoming book on aperiodic order. We review results about the topology, the dynamics, and the combinatorics of aperiodically ordered tilings obtained with the tools of noncommutative geometry.
