Abstract
In multihorizon black hole spacetimes, it is possible that there are degene rate Cauchy horizons with vanishing surface gravities. We investigate the s tability of the degenerate Cauchy horizon in black hole spacetimes. Despite the asymptotic behavior of spacetimes (flat, anti-de Sitter, or de Sitter) , we find that the Cauchy horizon is stable against the classical perturbat ions, but unstable quantum mechanically.
