Hamiltonian BRST formalism for gauge fields on black hole spacetimes
Karan Fernandes, Amitabha Lahiri
We investigate the Becchi-Rouet-Stora-Tyutin (BRST) formalism for gauge theories on spherically symmetric black hole spacetimes, with or without a cosmological constant ().…

Constrained field theories on Kerr backgrounds
Karan Fernandes, Amitabha Lahiri
We analyze the constraints of gauge theories on Kerr and Kerr-de Sitter spacetimes, which contain one or more horizons. We find that the constraints are modified on such background…
