Abstract
When two-dimensional Anti-de Sitter space (AdS(2)) is endowed with a non-co nstant dilaton the origin of the central charge in the Virasoro algebra gen erating the asymptotic symmetries of AdS(2) can be traced back to the break ing of the SL(2,R) isometry group of AdS(2). We use this fact to clarify so me controversial results appeared in the literature about the value of the central charge in these models. (C) 2000 Elsevier Science B.V. All rights r eserved.
