DESCRIPTION:Let _U_(_q_) be a Sylow _p_-subgroup of a Chevalle
y group _D__{4}(_q_)\, where _q_ is a powe
r of a prime _p_. We describe a construction of al
l complex irreducible characters of _U_(_q_) and o
btain a classification of these irreducible charac
ters via the root subgroups which are contained in
the center of these characters. Furthermore\, we
show that the multiplicities of the degrees of the
se irreducible\ncharacters are given by polynomial
s in _q_−1 with nonnegative coefficients.
