On Black Holes and Cosmological Constant in Noncommutative Gauge Theory of Gravity
M. Chaichian, M. R. Setare, A. Tureanu +1
Deformed Reissner-Nordström, as well as Reissner-Nordström de Sitter, solutions are obtained in a noncommutative gauge theory of gravitation. The gauge potentials (tetrad fields) a…
Noncommutative fields and actions of twisted Poincare algebra
M. Chaichian, P. P. Kulish, A. Tureanu +2
Within the context of the twisted Poincaré algebra, there exists no noncommutative analogue of the Minkowski space interpreted as the homogeneous space of the Poincaré group quotie…
Mirrorfolds with K3 Fibrations
Shinsuke Kawai, Yuji Sugawara
We study a class of non-geometric string vacua realized as completely soluble superconformal field theory (SCFT). These models are defined as `interpolating orbifolds' of $K3 \time…
Circumventing the No-Go Theorem in Noncommutative Gauge Field Theory
Masato Arai, Sami Saxell, Anca Tureanu +1
Stringent restrictions for model building are imposed by a no-go theorem in noncommutative gauge field theory. Circumventing this theorem is crucial for the construction of realist…
Corrections to Schwarzschild Solution in Noncommutative Gauge Theory of Gravity
M. Chaichian, A. Tureanu, G. Zet
A deformed Schwarzschild solution in noncommutative gauge theory of gravitation is obtained. The gauge potentials (tetrad fields) are determined up to the second order in the nonco…
Gauge-Dependence of Green's Functions in QCD and QED
K. Nishijima, A. Tureanu
When all Green's functions are known in a given gauge we may raise a question of whether it is possible or not to derive the corresponding ones in a different gauge. The answer is…
