Journal of Mathematics, Volume 2026, Issue 1, 2026.This paper develops the theory of function‐weighted probabilistic metric spaces (FWPMSs) and establishes the existence of common fixed points (CFPs) for commutative mappings within this framework. A key lemma is also introduced to bridge the connection between CFPs and common n‐tuples fixed points.

Dirac Theory in Noncommutative Phase Spaces
PhysicsBased on the position and momentum of noncommutative relations with a noncanonical map, we study the Dirac equation and analyze its parity and time reversal symmetries in a noncommutative phase space.

Zagadnienia Filozoficzne w Nauce, 2006 After briefly reviewing classical and quantum aspects of probability, basic concepts of the noncommutative calculus of probability (called also free calculus of probability) and its possible application to model the fundamental level of physics are ...

The existence of singularities and the origin of space-time
Zagadnienia Filozoficzne w Nauce, 2008 Methods of noncommutative geometry are applied to deal with singular space-times in general relativity. Such space-times are modeled by noncommutative von Neumann algebras of random operators.

Observables and dispersion relations in κ-Minkowski spacetime
Journal of High Energy Physics, 2017 We revisit the notion of quantum Lie algebra of symmetries of a noncommutative spacetime, its elements are shown to be the generators of infinitesimal transformations and are naturally identified with physical observables.

Self Sustained Traversable Wormholes Induced by Gravity’s Rainbow and Noncommutative Geometry
EPJ Web of Conferences, 2013 We compare the effects of Noncommutative Geometry and Gravity’s Rainbow on traversable wormholes which are sustained by their own gravitational quantum fluctuations. Fixing the geometry on a well tested model, we find that the final result shows that the

Balanced Metrics and Noncommutative Kähler Geometry
Symmetry, Integrability and Geometry: Methods and Applications, 2010 In this paper we show how Einstein metrics are naturally described using the quantization of the algebra of functions C^∞(M) on a Kähler manifold M. In this setup one interprets M as the phase space itself, equipped with the Poisson brackets inherited ...

B-decay anomalies and scalar leptoquarks in unified Pati-Salam models from noncommutative geometry
Journal of High Energy Physics, 2018 Motivated by possible scalar-leptoquark explanations of the recently reported B-decay anomalies, we investigate whether the required leptoquarks can be accommodated within models based on noncommutative geometry (NCG).

CPT breaking in noncommutative Magueijo-Smolin model
Nuclear Physics BWe review an instance of noncommutative geometry based on a specific realization of the model of doubly special relativity proposed by Magueijo and Smolin (MS) on noncommutative spacetime.

WKB Approximation in Noncommutative Gravity
Symmetry, Integrability and Geometry: Methods and Applications, 2007 We consider the quasi-commutative approximation to a noncommutative geometry defined as a generalization of the moving frame formalism. The relation which exists between noncommutativity and geometry is used to study the properties of the high-frequency ...
