When the obstruction is removed, there result quantal modifications to the constraints. The same classical theory gives rise to different quantum theories when different procedures for overcoming anomalies are implemented.10 pages in REVTeXGeneral Relativity and Quantum CosmologyHigh Energy Physics - Theorytext
