representable functor theorem

The **representable functor theorem** states that a Set-valued functor on a complete category is representable if and only if it is continuous and has a solution set?.

As representable functors are ubiquitous, this theorem is essentially equivalent to the adjoint functor theorem and to theorems guaranteeing the existence of limits.
