Noncommutative Deformation of General Relativity Ivan G. Avramidi (Department of Mathematics, New Mexico Tech) ABSTRACT:
We develop a novel approach to gravity in which
gravity is described by a matrix-valued symmetric two-tensor
field and construct an invariant functional
that reduces to the standard Einstein-Hilbert action in the
commutative limit. We also introduce a gauge symmetry
associated with the new degrees of freedom (gravicolor).
