A Note on Instantons in a 1D Same-Level Asymmetric Double Well
Klaus Bering
We prove formulas for the multi-instanton corrections to the overlap and energies of a 1D same-level asymmetric double well using the Euclidean path integral. Both the odd and even…
Semidensities, Second-Class Constraints and Conversion in Anti-Poisson Geometry
K. Bering
We consider Khudaverdian's geometric version of a Batalin-Vilkovisky (BV) operator Δ_E in the case of a degenerate anti-Poisson manifold. The characteristic feature of such an oper…
Putting an Edge to the Poisson Bracket
K. Bering
We consider a general formalism for treating a Hamiltonian (canonical) field theory with a spatial boundary. In this formalism essentially all functionals are differentiable from t…
BRST Formulation of Partition Function Constraints
J. Alfaro, K. Bering, P. H. Damgaard
We show that constraints on the generating functional have direct BRST-extensions in terms of nilpotent operators that annihilate this generating functional, and which may be o…
Gauge Independence of the Lagrangian Path Integral in a Higher-Order Formalism
I. A. Batalin, K. Bering, P. H. Damgaard
We propose a Lagrangian path integral based on gauge symmetries generated by a symmetric higher-order -operator, and demonstrate that this path integral is independent of the ch…
Sp(2)-Symmetric Lagrangian BRST Quantization
P. H. Damgaard, F. De Jonghe, K. Bering
One Lagrangian BRST quantization principle is that of imposing correct Schwinger-Dyson equations through the BRST Ward identities. In this paper we show how to derive the analogous…
