Abstract

The problem of determining the range of a given functor arises in various parts of mathematics.We present a sample of such problems, with focus on various functors, arising in the contexts of nonstable K_0-theory of rings, congruence lattices of universal algebras, spectral spaces of ring-like objects.We also sketch some of the ideas involved in the solutions of those problems.
