We analyze, in three space-time dimensions, the connection between Abelian self-dual
vector doublets and their counterparts containing both an explicit mass and a topological …

We study issues of duality and dual equivalence in noncommutative manifolds. In particular,
the question of dual equivalence for the actions of the noncommutative extensions of the self …

We show that the recently developed soldering formalism in the Lagrangian approach and
canonical transformations in the Hamiltonian approach are complementary. The examples …

The Sen formulation for chiral $(2p) $-form in $4 p+ 2$ dimensions describes a system with
two separate sectors, one is physical while the other is unphysical. Each contains a chiral …

We start this work by revisiting the problem of the soldering of two chiral Schwinger models
of opposite chiralities. We verify that, different from what one can conclude from the current …

We study issues of duality in 3D field theory models over a canonical noncommutative
spacetime and obtain the noncommutative extension of the self-dual model induced by the …

The classification of the regularization ambiguity of a 2D fermionic determinant in three
different classes according to the number of second-class constraints, including the new …

Superfields in 2-dimensional (2, 2)-superspace-time which are independent of (some) half of
the fermionic coordinates are discussed in a hopefully both comprehensive and …

We study issues of Lorentz violation symmetry in the context of the recently proposed theory
of noncommutative fields [J. Carmona, JL Cortés, J. Gamboa, and F. Méndes, J. High Energy …

We study a new mechanism for the electromagnetic gauging of chiral bosons showing that
new possibilities emerge for the interacting theory of chiral scalars. We introduce a chirally …
