Curvature in noncommutative geometry [PDF]
, 2019 Our understanding of the notion of curvature in a noncommutative setting has progressed substantially in the past ten years. This new episode in noncommutative geometry started when a Gauss-Bonnet theorem was proved by Connes and Tretkoff for a curved noncommutative two torus. Ideas from spectral geometry and heat kernel asymptotic expansions suggest a

LOCALITY, CAUSALITY AND NONCOMMUTATIVE GEOMETRY [PDF]
International Journal of Modern Physics A, 2006 We analyze the causality condition in noncommutative field theory and show that the nonlocality of noncommutative interaction leads to a modification of the light cone to the light wedge. This effect is generic for noncommutative geometry. We also check that the usual form of energy condition is violated and propose that a new form is needed in ...

Internal Space for the Noncommutative Geometry Standard Model and Strings [PDF]
, 2006 In this paper I discuss connections between the noncommutative geometry approach to the standard model on one side, and the internal space coming from strings on the other.

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.

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.

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 ...

Noncommutative Geometries and Gravity [PDF]
AIP Conference Proceedings, 2008 We briefly review ideas about ``noncommutativity of space-time'' and approaches toward a corresponding theory of gravity.
