Generalizes the BIZZ recursive procedure and provides sufficient conditions under which auxiliary field deformations of integrable sigma models retain classical Yangian symmetry and Maillet bracket structure.
A covariant quantization of the first-order Einstein-Hilbert theory is constructed via path integral and BV methods, with the connection as auxiliary field, yielding structural identities from Dyson-Schwinger equations and quantum equivalence to the second-order formulation at the effective action l

Covariant quantization of the Einstein-Hilbert theory in first-order form
A covariant quantization of the first-order Einstein-Hilbert theory is constructed via path integral and BV methods, with the connection as auxiliary field, yielding structural identities from Dyson-Schwinger equations and quantum equivalence to the second-order formulation at the effective action l
