Title: Exponentially localized Wannier functions: recent results and open
problems.

Abstract: Recent results concerning the problem of the existence of
exponentially localized Wannier functions are reviewed. In particular
the complete solution for the quasi one-dimensional case is given.
Some open problems are also discussed.
