A Remark on the Effective Description of Topological Defects
Jordi Paris, Jaume Roca
We subject the methodology used to derive the effective dynamics of topological defects to a critical reappraisal, using the two-dimensional kink as an illustrative example. Specia…
The BPHZ renormalised BV master equation and Two-loop Anomalies in Chiral Gravities
Frank De Jonghe, Jordi Paris, Walter Troost
Anomalies and BRST invariance are governed, in the context of Lagrangian Batalin-Vilkovisky quantization, by the master equation, whose classical limit is . Using Zimmerm…
Antibracket, Antifields and Gauge-Theory Quantization
Joaquim Gomis, Jordi Paris, Stuart Samuel
The antibracket formalism for gauge theories, at both the classical and quantum level, is reviewed. Gauge transformations and the associated gauge structure are analyzed in detail.…
BV analysis for covariant and non-covariant actions
C. Ordóñez, J. París, J. M. Pons +1
The equivalence between the covariant and the non-covariant version of a constrained system is shown to hold after quantization in the framework of the field-antifield formalism. O…
