✦ Synopsis

We investigate the important role of e ective projective objects in the study of (ÿnitary, multi sorted) varieties. In particular we give a new version of the classical Lawvere characterization Theorem and an application to the case of locally ÿnitely presentable categories.

In this note we give an example of a strictly convex, reflexive, smooth Banach space which has a Chebyshev subspace \(M\), such that the projection onto \(M\) is linear and has norm equal to 2 . Moreover, we give necessary and sufficient conditions on a space so that every projection has norm less t
