Key words Diffeomorphism invariant Colombeau algebra, point value characterization, pointvalues, algebras of generalized functions, invertibility of generalized functions, generalized numbers MSC (2010) 46F30We present a point value characterization for elements of the elementary full Colombeau algebra G e (Ω) and the diffeomorphism invariant full Colombeau algebra G d (Ω). Moreover, several results from the special algebra G s (Ω) about generalized numbers and invertibility are extended to the elementary full algebra.
