Non-Abelian Antisymmetric-Vector Coupling from Self-Interaction
A non-abelian coupling between antisymmetric fields and Yang-Mills fields
proposed by Freedman and Townsend several years ago is derived using the
self-interaction mechanism.Comment: 8 pages, latex, some misprints in the references are corrected.

Self-Dual Spin-3 And 4 Theories
We present self-dual spin-3 and 4 actions using relevant dreibein fields.
since these actions start with a Chern-Simons like kinetic term (and therefore
cannot be obtained through dimensional reduction) one might wonder whether they
need the presence of auxiliary ghost-killings fields. It turns out that they
must contain, also in this three dimensional case, auxiliary fields. They do
not break self-duality: their free actions do not contain kinetic second order
terms.Comment: 10, IC/91-20
Non-abelian self-duality from self-interaction

self-interaction mechanism.Comment: Latex, 7 page
Duality for massive spin two theories in arbitrary dimensions
Using the parent Lagrangian approach we construct a dual formulation, in the
sense originally proposed by Curtright and Freund, of a massive spin two
Fierz-Pauli theory in arbitrary dimensions . This is achieved in terms of a
mixed symmetry tensor , without the need of
auxiliary fields. The relation of this method with an alternative formulation
based on a gauge symmetry principle proposed by Zinoviev is elucidated. We show
that the latter formulation in four dimensions, with a given gauge fixing
together with a definite sequence of auxiliary fields elimination via their
equations of motion, leads to the parent Lagrangian already considered by West
completed by a Fierz-Pauli mass term, which in turns yields the
Curtright-Freund action. This motivates our generalization to arbitrary
dimensions leading to the corresponding extension of the four dimensional
result. We identify the transverse true degrees of freedom of the dual theory
and verify that their number is in accordance with those of the massive
Fierz-Pauli field.Comment: 14 pages, no figures, revtex 4. Some new comments and explanations
have been added and the notation homogeneize
Topological mass in seven dimensions and dualities in four dimensions
The massive topologically and self dual theories en seven dimensions are
considered. The local duality between these theories is established and the
dimensional reduction lead to the different dualities for massive antisymmetric
fields in four dimensions.Comment: 7 page
Massive Gauge Axion Fields
A gauge invariant formulation for the massive axion is considered. The axion
acquires mass through a topological term which couples a (pseudo)scalar and a
third rank antisymmetric tensor. Duality, local and canonical equivalences with
the non-gauge invariant proposal are established. The supersymmetric version of
the gauge invariant model is constructed.Comment: Final version. New references adde
Dualization of non-Abelian BF model
We show that dualization of BF models to Stueckelberg-like massive gauge
theories allows a non-Abelian extension. We obtain local Lagrangians which are
straightforward extensions of the Abelian results.Comment: 6 pages, ReVTeX, no figures, to be publ. on Phys.Lett.
A non local unitary vector model in 3-D
We present a unified analysis of single excitation vector models in 3D. We
show that there is a family of first order master actions related by duality
transformations which interpolate between the different models. We use a
Hamiltonian (2+1) analysis to show the equivalence of the self-dual and
topologically massive models with a covariant non local model which propagates
also a single massive excitation. It is shown how the non local terms appears
naturally in the path integral framework.Comment: 13 pages, 1 figur
