Generalized Bargmann-Wigner equations in curved space-time

The Bargmann-Wigner equations are formulated to represent bosonic fields in terms of fermionic fields in curved space-time. The bispinor field is explicitly studied including lower spin states. The correspondence among fermions and bosons through bispinors is applied to the superradiance problem in Kerr black-hole spacetime. Superradiance phenomena of the type of positive frequency (0 < ω ) and negative momentum near the horizon ( p H < 0) are shown not to occur.
