We obtain asymptotic formulas with remainder terms for the hyperbolic summations \(\sum _{mn\le x} f((m,n))\) and \(\sum _{mn\le x} f([m,n])\), where f belongs to certain classes of arithmetic functions, (mn) and [mn] denoting the gcd and lcm of the integers mn. In particular, we investigate the functions \(f(n)=\tau (n), \log n, \omega (n)\) and \(\Omega (n)\). We also define a common generalization of the latter three functions, and prove a corresponding result.

关于包含两个正整数的GCD和LCM的算术函数的某些和

我们为双曲求和\(\ sum _ {mn \ le x} f((m,n))\)\(\ sum _ {mn \ le x} f([m,n ])\),其中f属于某些算术函数类,(m,  n)和[ m,  n ]表示整数m,  n的gcd和lcm 。特别地,我们研究函数\(f(n)= \ tau(n),\ log n,\ omega(n)\)\(\ Omega(n)\)。我们还定义了后三个函数的通用概括,并证明了相应的结果。
