In this paper, we investigate the moments of Hurwitz class numbers in relation to fixed arithmetic progressions of imaginary quadratic orders. Specifically, we examine the ratio of the 2k-th moment to the zeroeth moment for H(4n - t2) as n varies, where t is fixed in an arithmetic progression t = m (mod M). As a consequence, we obtain asymptotic formulas for moments of the trace t = m (mod M) of Frobenius on elliptic curves over finite fields with pr elements when n = pr.
In this paper, we study moments of Hurwitz class numbers associated to imaginary quadratic orders restricted into fixed arithmetic progressions. In particular, we fix t in an arithmetic progression t = m (mod M) and consider the ratio of the 2k-th moment to the zeroeth moment for H(4n - t2) as one varies n. The special case n = pr yields as a consequence asymptotic formulas for moments of the trace t = m (mod M) of Frobenius on elliptic curves over finite fields with pr elements.
