Abstract
We investigate the important role of effective projective objects in the st udy of(finitary multi sorted) varieties. In particular we give a new versio n of the classical Lawvere characterization Theorem and an application to t he case of locally finitely presentable categories. (C) 2001 Elsevier Scien ce B.V.
