Comments on noncommutative gravity
Luis Alvarez-Gaume, Frank Meyer, Miguel A. Vazquez-Mozo
We study the possibility of obtaining noncommutative gravity dynamics from string theory in the Seiberg-Witten limit. We find that the resulting low-energy theory contains more int…
Twisted Gauge Theories
Paolo Aschieri, Marija Dimitrijevic, Frank Meyer +2
Gauge theories on a space-time that is deformed by the Moyal-Weyl product are constructed by twisting the coproduct for gauge transformations. This way a deformed Leibniz rule is o…
Noncommutative Geometry and Gravity
Paolo Aschieri, Marija Dimitrijevic, Frank Meyer +1
We study a deformation of infinitesimal diffeomorphisms of a smooth manifold. The deformation is based on a general twist. This leads to a differential geometry on a noncommutative…
Noncommutative Spaces and Gravity
Frank Meyer
This is an introduction to an algebraic construction of a gravity theory on noncommutative spaces which is based on a deformed algebra of (infinitesimal) diffeomorphisms. We start…
A Gravity Theory on Noncommutative Spaces
Paolo Aschieri, Christian Blohmann, Marija Dimitrijevic +3
A deformation of the algebra of diffeomorphisms is constructed for canonically deformed spaces with constant deformation parameter theta. The algebraic relations remain the same, w…
Gauge Theory on Fuzzy S^2 x S^2 and Regularization on Noncommutative R^4
Wolfgang Behr, Frank Meyer, Harold Steinacker
We define U(n) gauge theory on fuzzy S^2_N x S^2_N as a multi-matrix model, which reduces to ordinary Yang-Mills theory on S^2 x S^2 in the commutative limit N -> infinity. The mod…
