Abstract

We present a geometric approach to defining an algebra (M) (the Colombeau algebra) of generalized functions on a smooth manifold M containing the space ?(M) of distributions on M.
Based on differential calculus in convenient vector spaces we achieve an intrinsic construction of (M). (M) is a differential algebra, its elements possessing Lie derivatives with respect to arbitrary smooth vector fields. Moreover, we construct a canonical linear embedding of ?(M) into (M) that renders ?(M) a faithful subalgebra of (M). Finally, it is shown that this embedding commutes with Lie derivatives. Thus (M ) retains all the distinguishing properties of the local theory in a global context.
