摘要
In non-extreme Kerr-Newman-Ad S spacetime, we prove that there is no nontrivial Dirac particle which is Lpfor 0 < p≤ 4/3 with arbitrary eigenvalue λ, and for 4/3< p≤ 4/(3-2q), 0 < q <3/2 with eigenvalue|λ| > |Q| + qκ, outside and away from the event horizon. By taking q =1/2, we show that there is no normalizable massive Dirac particle with mass greater than |Q| +κ/2 outside and away from the event horizon in non-extreme Kerr-Newman-Ad S spacetime, and they must either disappear into the black hole or escape to infinity, and this recovers the same result of Belgiorno and Cacciatori in the case of Q = 0 obtained by using spectral methods.Furthermore, we prove that any Dirac particle with eigenvalue |λ| <κ/2 must be L^2 outside and away from the event horizon.
