Geometrical aspects of the BRST quantization of charged antisymmetric tensor fields and string fields are studied within the framework of the Batalin and Vilkovisky method. In both cases, candidate anomalies which obey the Wess-Zumino consistency conditions are given.

    • "It was already noticed in the past that, when one quantizes charged-forms, all relevant fields and antifields fit in a unifying formalism, which generalizes that of the genuine Yang–Mills case (see e.g. [2] and [3]). However, the invariant classical actions found in [3] were first order, and describe fields with vanishing curvatures. "

    ABSTRACT: We describe forms with non-Abelian charges. We avoid the use of theories with flat curvatures by working in the context of topological field theory. We obtain TQFTs for a form and its dual. We leave open the question of getting gauges in which the form, or its dual, can be gauged away, in such way that the model has two dual formulations. We give the example of charged two-forms in six dimensions. Comment: 11 pages, harvmac file

    • "A model that has been intensively studied from the Lagrangian point of view is the Freedman-Townsend model. Its main interest lies in the fact that (i) it is equivalent to the non-linear σ-model [12], (ii) the algebraic structure of its gauge symmetries is similar to that of Witten's string theory [13], (iii) even if its BRST structure is well understood [14] [15] [16], the attemps to incorporate the anti-BRST symmetry have not been entirely satisfactory [17]. Our purpose in this article is to illustrate the general Lagrangian BRST-anti- BRST method in the case of this representative model. "

    ABSTRACT: The quantization of Witten's bosonic string field theory is studied by using a generalized BRST approach. We constructed an off-shell nilpotent BRST transformation by introducing a set of auxiliary fields, and found the form of the corresponding gauge-fixed action.
