Asymmetric noncommutative torus has vanishing Einstein tensor
Deeponjit Bose, Andrzej Sitarz
We explicitly compute the spectral metric, torsion and Einstein tensors for a nontrivial spectral triple on a noncommutative torus, with the Dirac operator related to the fully equ…

Fate of -Minkowski space-time in non-relativistic (Galilean) and ultra-relativistic (Carrollian) regimes
Deeponjit Bose, Anwesha Chakraborty, Biswajit Chakraborty
Here, we present an algebraic and kinematical analysis of non-commutative -Minkowski spaces within Galilean (non-relativistic) and Carrollian (ultra-relativistic) regimes. Util…
