A generalization of the well-known problem of he construction of complete full bi-involutive sets of polynomials on the conjugate space of a Lie algebra to the case of singular covectors is considered. A generalization of the Mishchenko–Fomenko method of argument shift to the case of singular covectors if proposed and sufficient conditions for the completeness of the resulting sets are found. Using this method, it is shown that complete bi-involutive sets of polynomials can be constructed for singular covectors in all reductive Lie algebras.
