DO NAKED SINGULARITIES FORM

A naked singularity is formed by the collapse of a sine-Gordon soliton in (1+1)-dimensional dilaton gravity with a negative cosmological con stant. We examine the quantum stress tensor resulting from the formati on of the singularity. Consistent boundary conditions require that the incoming soliton is accompanied by a flux of incoming radiation acros s past null infinity, but neglecting the back reaction of me spacetime leads to the absurd conclusion that the total energy entering the sys tem by the time the observer is able to receive information from the s ingularity is infinite. We conclude that the back reaction must preven t the formation of the naked singularity.
