All rings are assumed to be finite commutative with identity element. An element a ? R is called a regular element if there exists b ? R such that a = a2b, the element b is called a von Neumann inverse for a. A characterization is given for regular elements and their inverses in Zn, the ring of...

For the number of integer solutions of the title equation, with W ? x (x a large parameter), an asymptotics of the form Ax log x + Bx + O(x1/2(log x)ï¿½(log log x)ï¿½) is established. This is achieved in a general setting which furnishes applications to some other natural arithmetic functions.

An integer d = ?si=1 pbii is called the exponential divisor of n = ?si=1 paii > 1 if bijai for every i ? {1, 2, ï¿½, s}. Let t (e)(n) denote the number of exponential divisors of n, where t(e)(1) = 1 by convention. The aim of this paper is to establish a short interval result for for...

We provide a general asymptotic formula which permits applications to sums like ["Multiple line equation(s) cannot be represented in ASCII text"]. where d(n) and r(n) are the usual arithmetic functions (number of divisions, sums of two squares), and y is small compared to x.

Defining outliers by their distance to neighboring data points has been shown to be an effective non-parametric approach to outlier detection. In recent years, many research efforts have looked at developing fast distance-based outlier detection algorithms. Several of the existing distance-based...

- RANK EQUALITIES FOR MOORE-PENROSE INVERSE AND DRAZIN INVERSE OVER QUATERNION. HUASHENG ZHANG // Annals of Functional Analysis;2012, Vol. 3 Issue 2, p115
In this paper, we consider the ranks of four real matrices Gi(i = 0; 1; 2; 3) in M, where M = M0+M1i+M2j+M3k is an arbitrary quaternion matrix, and My = G0 + G1i + G2j + G3k is the Moore-Penrose inverse of M. Similarly, the ranks of four real matrices in Drazin inverse of a quaternion matrix are...
