A general form of higher-order contributions (in &) to the Einstein field equations is displayed. The additional terms may either stabilize or destabilize self-gravitating objects in gravitational collapse depending on the sign of the coefficient introducing the quadratic term. If the quadratic term
## Abstract We consider a string stretched between two diagonal branes on a bosonic torus under a perturbation of one of the radii. In the worldβsheet description, this corresponds to a perturbation of a conformal field theory with two boundary components. A term in the second order boundary RG equ
