Let R be a ring of algebraic integers of an algebraic number
field F and let be a finite group. In [11] was proved that
the R-span of G is just the matrix ring
of the
over R if and only if the Brauer
reduction of
modulo every prime is absolutely
irreducible. In this paper, we show that
if and only if the Brauer reduction of
modulo a finite number of primes is
absolutely irreducible. Moreover, we give conditions for n,
under which
is a Schur ring.
