SINCE Olsen and Lempel constructed a family of optimal key sequences (called Bent se-quences) by using the trace function over finite field in 1982, the theory of trace functionhas been widely used in spread-spectrum ...
USING the method of probabilistic number-theory, De Koninck, and De Koninck and Galambos studied the reciprocal sum of the additive function f(n) satisfying f(n)≥t0>0 (n≥2) and f(p)≡1 and obta...

where α_n and β_n are integers with 0≤α_n<β_n≤n. For an i.i.d, sequence {X_n}, many authors studied the asymptotic behavior of the trimmed sums T_n. In this note, we try extending the research extent in two d...

Let p(n) and Q(n) stand for the smallest and the largest prime factors of the natural number n, respectively. Recently, the sums involving reciprocals of the functions p(n) and Q(n) were studied by Erds, Ivié et al. ...
1 Introduction Let x be a large real number. Study of the famous Dirichlet’s divisor problem suggests that for positive integers n≤x. Distribution of {x/n} in [0, 1) is fairly even. For any given real number α sati...

1 Introduction Suppose q≥5 is an odd number, for any integers a, (a, q)=1, a stands for the solution of congruence ax≡1(modq) in the interval 1≤x≤q-1. We denote L(q) by L(q)={a|a∈Z, 1≤a≤q-1, (a, q)=1, a+a≡1 (m...

It is well known that there are many authors who have thoroughly investigated the complete convergence for non-random partial sums of i. i. d. random variables, such as Katz and Baum, BAI Zhi-dong and SHU Chun. In [2]...
