Normalization of Killing vectors and energy conservation in two-dimensional gravity - art. no. 107506

We explicitly show that, in the context of a recently proposed two-dimensio nal dilaton gravity theory, energy conservation requires the "natural" Kill ing vector to have, asymptotically, an unusual normalization. The Hawking t emperature T-H is then calculated according to this prescription. [S0556-28 21(99)04218-6].
