Abstract
Corings are algebras (or monoids) in the opposite of the category of corings.
We present several examples, and introduce the notion of grouplike element.
A Galois coring is a coring with a grouplike element, such that a certain map,
called the canonical map is bijective. The definition is motivated using descent
theory, and can be used to provide an elementary reformulation of Galois
descent theory and some of its generalizations.
