General Lagrangian formulations for mixed-antisymmetric tensor fields on flat backgrounds
First presentation of unconstrained and constrained gauge Lagrangian formulations for irreducible and reducible higher-spin Poincare representations with mixed-antisymmetric indices via BRST with complete and incomple...

BRST methods for constructing quartic actions for spinning black holes
A BRST formulation yields a single constraint per off-shell quartic vertex ensuring gauge invariance and associativity, with example solutions for low-spin cases in black hole scattering.

General Lagrangian formulations for mixed-antisymmetric tensor fields on flat backgrounds
Lagrangian formulations for mixed-antisymmetric higher-spin fields with k-column Young tableaux are constructed via complete and incomplete BRST operators after converting constraints using Verma modules and Howe duality.
