Abstract
General relativity in three or more dimensions can be obtained by taking the limit in the Brans--Dicke theory. In two dimensions general relativity is an unacceptable theory. We show that the two-dimensional closest analogue of general relativity is a theory that also arises in the limit of the two-dimensional Brans--Dicke theory.Keywords
