Hamiltonian and Lagrangian BRST Quantization in Riemann Manifold II
We have previously developed the BRST quantization on the hypersurface VN−1 embedded in N-dimensional Euclidean space RN in both Hamiltonian and Lagrangian formulation.

We obtain the off-shell nilpotent Becchi–Rouet–Stora–Tyutin (BRST) and anti-BRST symmetry transformations (corresponding to the infinitesimal classical gauge symmetry transformations) for the modified massive three 2+1-dimensional (3D) Abelian two-form ...

On the BPS Sector in AdS3/CFT2 Holography
Abstract The BPS sector in AdS3/CFT2$AdS_3/CFT_2$ duality has been fertile ground for the exploration of gauge/gravity duality, from the match between black hole entropy and the CFT elliptic genus to the construction of large families of geometrical microstates and the identification of the corresponding states in the CFT.

Homotopy Transfer and Effective Field Theory II: Strings and Double Field Theory
Abstract We continue our study of effective field theory via homotopy transfer of L∞$L_\infty$‐algebras, and apply it to tree‐level non‐Wilsonian effective actions of the kind discussed by Sen in which the modes integrated out are comparable in mass to the modes that are kept. We focus on the construction of effective actions for string states at fixed

The one-loop unimodular graviton propagator in any dimension
For unimodular gravity, we work out, by using dimensional regularization, the complete one-loop correction to the graviton propagator in any space-time dimension.

BRST-ANTIFIELD QUANTIZATION: A SHORT REVIEW [PDF]
Most of the known models describing the fundamental interactions have a gauge freedom. In the standard path integral, it is necessary to "fix the gauge" in order to avoid integrating over unphysical degrees of freedom. Gauge independence might then become a tricky issue, especially when the structure of the gauge symmetries is intricate.

Nilpotent Symmetries of a Model of 2D Diffeomorphism Invariant Theory: BRST Approach
Within the framework of the Becchi‐Rouet‐Stora‐Tyutin (BRST) formalism, we discuss the full set of proper BRST and anti‐BRST transformations for a 2D diffeomorphism invariant theory which is described by the Lagrangian density of a standard bosonic string. The above (anti‐)BRST transformations are off‐shell nilpotent and absolutely anticommuting.

Superfield Approaches to a Model of Bosonic String: Curci‐Ferrari‐Type Restrictions
Exploiting the theoretical potential of the modified Bonora‐Tonin superfield approach (MBTSA) as well as the (anti‐)chiral superfield approach (ACSA) to Becchi‐Rouet‐Stora‐Tyutin (BRST) formalism, we derive the complete set of off‐shell nilpotent (anti‐)BRST symmetry transformations corresponding to the classical two‐ (1 + 1) dimensional (2D ...

Double Copy from Homotopy Algebras
It will be shown that the BRST Lagrangian double copy construction of N = 0 supergravity as the ‘square’ of Yang–Mills theory finds a natural interpretation in terms of homotopy algebras. The authors significantly expand on their previous work arguing the validity of the double copy at the loop level, and they give a detailed derivation of the double ...
