Renormalization of non-locally regularized BRST-anti-BRST theories
V. Calian, G. Stoenescu
An extension of the non-local regularization scheme is formulated in the Sp(2) symmetric Lagrangian BRST quantization framework. It generates a systematic treatment of the anomalou…

Integrable hierarchies from BRST-anti-BRST gauge-fixing
V. Calian
The BRST formulation is used in order to derive the existence criterion for classical bi-Hamiltonian systems, based on non-anomalous deformation of the gauge-fixing structure. The…
