We complete a proof of Colmez, showing that the standard
product formula for algebraic numbers has an analog for periods of CM
abelian varieties with CM by an abelian extension of the rationals. The
proof depends on explicit computations with the De Rham cohomology of
Fermat curves, which in turn depends on explicit computation of their
stable reductions.
