Gauge theory on ρ-Minkowski space-time

Journal of High Energy Physics
We construct a gauge theory model on the 4-dimensional ρ-Minkowski space-time, a particular deformation of the Minkowski space-time recently considered. The corresponding star product results from a combination of Weyl quantization map and properties of ...

Direct Bethe-Salpeter solutions in Minkowski space

EPJ Web of Conferences, 2016
We review a method to directly solve the Bethe-Salpeter equation in Minkowski space, both for bound and scattering states. It is based on a proper treatment of the many singularities which appear in the kernel and propagators.

Elastic Sturmian spirals in the Lorentz-Minkowski plane

Open Mathematics, 2016
In this paper we consider some elastic spacelike and timelike curves in the Lorentz-Minkowski plane and obtain the respective vectorial equations of their position vectors in explicit analytical form.

Langevin simulation in Minkowski space?

Physics Letters B, 1985
Abstract We present in this paper a “tentative”, “formal” proof that the Langevin simulation for relativistic systems can be performed directly in Minkowski space without rotating to euclidean time. The proof bypasses the difficult task of studying the spectrum of the non-self-adjoint Fokker-Planck hamiltonian and it is based on a dimensional ...

Generalized open sets of Minkowski space [PDF]

Mathematica Moravica, 2015
We consider the Euclidean topology and s-topology on n-dimensional Minkowski space and investigate the interior and closure of the space cone and perforated space cone with respect to these topologies.

Tzitzeica-Type centro-affine invariants in Minkowski spaces

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
In this article we introduce three centro-affine invariant functions in Minkowski spaces. Tzitzeica curves and Tzitzeica surfaces may be defined in this new context.

Einstein’s physical chronogeometry

Manuscrito
In Einstein’s physical geometry, the geometry of space and the uniformity of time are taken to be non-conventional. However, due to the stipulation of the isotropy of the one-way speed of light in the synchronization of clocks (or definition of ...

Bubble universe from flat spaces

European Physical Journal C: Particles and Fields
We show by matching two flat spaces one in Minkowski coordinates ( empty space) and the other in Minkowski coordinates after a special conformal transformation (also empty space) through a bubble with positive and constant surface tension, that the ...

A Theory of Gravity in Minkowski Space

Gravitation and Cosmology
In this paper, we present a theory of gravity in Minkowski space. The basic idea is that the presence of mass affects the worldline of particles in the flat Minkowski background. Although General Relativity is in complete agreement with observations so far, the theory discussed in this paper is capable of solving some of the conceptual difficulties of ...
