Abstract
We consider the quasi-commutative approximation to a
noncommutative geometry defined as a generalization of the moving frame formalism. The relation which exists between noncommutativity and geometry is used to study the properties of the high-frequency waves on the flat background.
Key words:
noncommutative geometry; models of quantum gravity.
