κ -Minkowski representations on Hilbert spaces [PDF]
Journal of Mathematical Physics, 2007 The algebra of functions on κ-Minkowski noncommutative space-time is studied as algebra of operators on Hilbert spaces. The representations of this algebra are constructed and classified. This new approach leads to a natural construction of integration in κ-Minkowski space-time in terms of the usual trace of operators.

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.

Spectral geometry of κ-Minkowski space [PDF]
Journal of Mathematical Physics, 2006 After recalling Snyder’s idea [Phys. Rev. 71, 38 (1947)] of using vector fields over a smooth manifold as “coordinates on a noncommutative space,” we discuss a two-dimensional toy-model whose “dual” noncommutative coordinates form a Lie algebra: this is the well-known κ-Minkowski space [Phys. Lett. B 334, 348 (1994)].

Einstein’s physical chronogeometry
ManuscritoIn 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 FieldsWe 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 ...

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.

Conformal partial wave expansion of celestial correlators
Journal of High Energy PhysicsA novel definition of holographic correlation functions on the celestial sphere of Minkowski space was recently introduced in [1] as the extrapolation of bulk time-ordered correlation functions to the celestial sphere.
