Ranges of functors in algebra

Résumé

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.
