Weighted first moments of some special quadratic Dirichlet -functions
In this paper, we obtain asymptotic formulas for weighted first moments of
central values of families of primitive quadratic Dirichlet -functions whose
conductors comprise only primes that split in a given quadratic number field.
We then deduce a non-vanishing result of these -functions at the point

First Moment of Hecke -functions with quartic characters at the central point
In this paper, we study the first moment of central values of Hecke
-functions associated with quartic characters.Comment: 11 page
One level density of low-lying zeros of quadratic and quartic Hecke -functions
In this paper, we prove some one level density results for the low-lying
zeros of famliies of quadratic and quartic Hecke -functions of the Gaussian
field. As corollaries, we deduce that, respectively, at least and
of the members of the quadratic family and the quartic family do not
vanish at the central point.Comment: 25 pages. arXiv admin note: text overlap with arXiv:0910.506
