Abstract:

Dilaton gravity in two dimensions is briefly reviewed from the perspective of three dilaton potentials: One determines classical physics (``the good'', denoted by $w$), the second is relevant for semi-classical (and quantum) effects (``the muggy'', denoted by $I$) and the third could be responsible for nonperturbative quantum effects (``the bad'', denoted by $Z$).

This paper is based upon lectures given in Cernowitz in October/November 2002 at The XIV International Hutsulian Workshop ``Mathematical Theories and their Physical & Technical Applications''.
