We also show that the given field redefinitions yield the Baulieu-Singer formulation of Topological Yang Mills theory when after an instanton inspired truncation of the theory is used.6 pages, talk given at the International Workshop "Supersymmetries and Quantum Symmetries" (SQS'05), JINR, Dubna, July 27-31 2005; to appear in the proceedings of SQS'05High Energy Physics - Theorytext
