Abstract
We give a detailed description of the nested algebraic Bethe ansatz. We consider integrable models with a -invariant -matrix as the basic example, however, we also describe possible generalizations. We give recursions and explicit formulas for the Bethe vectors. We also give a representation for the Bethe vectors in the form of a trace formula.
