We show that the Becchi-Rouet-Stora-Tyutin (BRST)/anti-BRST invariant (3+ 1)-dimensional
two-form gauge theory has further nilpotent symmetries (dual BRST/anti-dual BRST) that …

Currently, there is much interest in discovering analytically tractable (3+ 1)-dimensional
models that describe interacting fermions with emerging topological properties. Towards that …

It is shown that the four (3+ 1)-dimensional (4D) free Abelian 2-form gauge theory provides
an example of (i) a class of field theoretical models for the Hodge theory, and (ii) a possible …

Following the symplectic approach we show how to embed the Abelian Proca model into a
first-class system by extending the configuration space to include an additional pair of scalar …

We show that the BFT embedding method is problematic for mixed systems (systems
possessing both first and second class constraints). The Chern-Simons theory as an …

We propose a method in the context of BFFT approach that leads to truncation of the infinite
series regarded as constraints in the extended phase space, as well as other physical …

We analyze the equivalence between topologically massive gauge theory (TMGT) and
different formulations of non-topologically massive gauge theories (NTMGTs) in the …

Since Dirac proposed quantization for systems with constraints, there have been
considerable progresses in Hamiltonian quantization method associated with Becchi-Rouet …

We study the duality symmetry in p-form models containing a generalized Bq∧ Fp+ 1 term in
spacetime manifolds of arbitrary dimensions. The equivalence between the Bq∧ Fp+ 1 self …

We have constructed a modified BFT method that preserves the chain structure of
constraints. This method has two advantages: first, it leads to less number of primary …
