Star-products for Lie-algebraic noncommutative Minkowski space-times
Valentine Maris, Filip Požar, Jean-Christophe Wallet
Poisson structures of the Poincaré group can be linked to deformations of the Minkowski space-time, classified some time ago by Zakrewski. Based on this classification, various qua…

Corrections to Kerr-Newman black hole from Noncommutative Einstein-Maxwell equation
Filip Požar
In this letter we introduce the noncommutative geometry into the standard Einstein-Hilbert-Maxwell action via the Drinfeld twist and solve the equation…

Entropy of black holes, charged probes and noncommutative generalization
Axel Hrelja, Tajron Jurić, Filip Požar
The brick wall model is a semi-classical approach to understanding the microscopic origin of black hole entropy. We outline the formalism for the brick wall model in arbitrary numb…
