extent still eluding a rigorous treatment. By restricting to ideal,
zero-temperature situations, one resorts to consider suitable classes of
particle-interaction functionals. Crystallization then corresponds to prove
the periodicity of the minimizers of such functionals. In some
distinguished cases, this variational perspective can shed light on the
global geometry and the mechanics of crystalline solids. I will review some
classical results on crystallization, highlight recent advances, and
comment on the many open questions.
