Abstract

We present a covariant canonical formalism for noncommutative gravity, and in general for noncommutative geometric theories defined via a twisted \star-wedge product between forms. Noether theorems are generalized to the noncommutative setting, and gauge generators are constructed in a twisted phase space with \star-deformed Poisson bracket. This formalism is applied to noncommutative d=4d=4 vierbein gravity, and allows to find the canonical generators of the tangent space \star-gauge group.
