Curvature in Noncommutative Geometry [PDF]
, 2020 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 Geometry and Gravity [PDF]
Classical and Quantum Gravity, 2005 We study a deformation of infinitesimal diffeomorphisms of a smooth manifold. The deformation is based on a general twist. This leads to a differential geometry on a noncommutative algebra of functions whose product is a star-product.

Locality, Causality and Noncommutative Geometry [PDF]
International Journal of Modern Physics A, 2005 We analyse 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.

Applied Latin Hypercube stochastic method to quantify the uncertainty in groundwater equation model simulations [PDF]
E3S Web of Conferences, 2021 It is accepted that digital models simplify the physical reality that is the object of the modeling. Hydrodynamic modeling is an approach with high uncertainties in this context.

Groundwater flow equation, overview, derivation, and solution [PDF]
E3S Web of Conferences, 2021 Darcy’s law is the basic law of flow, and it produces a partial differential equation is similar to the heat transfer equation when coupled with an equation of continuity that explains the conservation of fluid mass during flow through a porous media ...

A study of water infiltration basin and clogging using column experiments [PDF]
E3S Web of Conferences, 2021 The clogging of infiltration basins is the main problem affecting the proper functioning of groundwater artificial recharge systems. In this study, several parameters have been varied to understand their impacts on water infiltration.

Oberwolfach Reports, 2008 Noncommutative geometry applies ideas from geometry to mathematical structures determined by noncommuting variables. Within mathematics, it is a highly interdisciplinary subject drawing ideas and methods from many areas of mathematics and physics. Natural questions involving noncommuting variables arise in abundance in many parts of mathematics and ...

One-loop corrections to the spectral action
Journal of High Energy Physics, 2022 We analyze the perturbative quantization of the spectral action in noncommutative geometry and establish its one-loop renormalizability in a generalized sense, while staying within the spectral framework of noncommutative geometry. Our result is based on

Wormhole inspired by non-commutative geometry
Physics Letters B, 2015 In the present Letter we search for a new wormhole solution inspired by noncommutative geometry with the additional condition of allowing conformal Killing vectors (CKV).

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.
