Abstract: | We study differential operators with coefficients in noncommutative algebras. As an algebra of coefficients, we consider crossed
products corresponding to the action of a discrete group on a smooth manifold. We give index formulas for the Euler, signature,
and Dirac operators twisted by projections over the crossed product. The index of Connes operators on the noncommutative torus
is computed. |
