摘要: The semi-classical stability of several AdS NUT instantons is studied. Throughout, the notion that at one-loop level Euclidean quantum gravity. Instabilities manifest themselves as negative eigenmodes a modified Lichnerowicz Laplacian acting on transverse, traceless perturbations. An instability found for one branch AdS-Taub-Bolt family metrics and it argued other stable. It also AdS-Taub-NUT A component continuous spectrum operator all three families found.
