Let ζ(s) denote the Riemann zeta-function. This thesis is concerned with estimating discrete moments of the form JkT= 1NT 0 0 arbitrary, there exist positive constants C1 = C1(k) and C2 = C2( k, ϵ) such that the inequalities C1logT kk+2≤Jk T≤C2 logTk k+2+3 hold when T is sufficiently large. The lower bound for Jk(T) was proved jointly with Nathan Ng.;Two related problems are also considered. Assuming the Riemann Hypothesis S. M. Gonek has shown that J1(T) ∼ 112logT 3 as T → ∞. As an application of the L-functions Ratios Conjectures, J.B. Conrey and N. Snaith made a precise conjecture for the lower-order terms in the asymptotic expression for J 1(T). By carefully following Gonek's original proof, we establish their conjecture.;The other problem is related to the average of the mean square of the reciprocal of ζ′(ρ). It is believed that the zeros of ζ(s) are all simple. If this is the case, then the sum Jk(T) is defined when k < 0 and, for certain small values of k, conjectures exist about its behavior. Assuming the Riemann Hypothesis and that the zeros of ζ(s) are simple, we establish a lower bound for J-1(T) that differs from the conjectured value by a factor of 2.

Gonek表明J1(T)〜112logT 3为T→∞。作为L函数比率猜想的一种应用,J.B。Conrey和N. Snaith对J 1(T)的渐近表达式中的低阶项做出了精确的猜想。通过仔细地遵循Gonek的原始证明,我们建立了它们的猜想。另一个问题与ζ′(ρ)的倒数的均方均值有关。相信ζ(s)的零都是简单的。如果是这种情况,则当k <0时定义和Jk(T),并且对于k的某些小值,存在关于其行为的猜想。假设黎曼假设和ζ(s)的零很简单,我们为J-1(T)建立了一个下界,该下界与推测值相差2倍。
