The fuzzy BTZ
Ilija Buric, Maja Buric
We introduce a model of a noncommutative BTZ black hole, obtained by quantisation of Poincaré coordinates together with a moving frame. The fuzzy BTZ black hole carries a covariant…
Laplacian on fuzzy de Sitter space
Bojana Brkic, Maja Buric, Dusko Latas
We study details of geometry of noncommutative de Sitter space: we determine the Riemann and Ricci curvature tensors, the energy and the Laplacian. We find, in particular, that fuz…
Discrete fuzzy de Sitter cosmology
Maja Buric, Dusko Latas
We analyze the spectrum of time observable in noncommutative cosmological model introduced in [5], defined by representation of the de Sitter group. We find tha…
One-loop structure of the U(1) gauge model on the truncated Heisenberg space
Maja Burić, Luka Nenadović, Dragan Prekrat
We calculate divergent one-loop corrections to the propagators of the U(1) gauge theory on the truncated Heisenberg space, which is one of the extensions of the Grosse-Wulkenhaar m…
Noncommutative de Sitter and FRW spaces
Maja Buric, John Madore
Several versions of fuzzy four-dimensional de Sitter space are constructed using the noncommutative frame formalism. Although all noncommutative spacetimes which are found have com…
Spinors on a curved noncommutative space: coupling to torsion and the Gross-Neveu model
Maja Buric, John Madore, Luka Nenadovic
We analyse the spinor action on a curved noncommutative space, the so-called truncated Heisenberg algebra, and in particular, the nonminimal coupling of spinors to the torsion. We…
