Values of the Euler Function in Various Sequences
Let ’ðnÞ and ðnÞ denote the Euler and Carmichael functions, respectively. In this paper, we investigate the equation ’ðnÞ 1⁄4 ðnÞ, where r 5 s5 1 are fixed positive integers. We also study those positive integers n, not equal to a prime or twice a prime, such that ’ðnÞ 1⁄4 p 1 holds with some prime p, as well as those positive integers n such that the equation ’ðnÞ 1⁄4 f ðmÞ holds with some int...
متن کاملinterpersonal function of language in subtitling
translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
15 صفحه اولSmall values of the Euler function and the Riemann hypothesis
Let φ be Euler’s function, γ be Euler’s constant and Nk be the product of the first k primes. In this article, we consider the function c(n) = (n/φ(n)−eγ log log n) √ log n. Under Riemann’s hypothesis, it is proved that c(Nk) is bounded and explicit bounds are given while, if Riemann’s hypothesis fails, c(Nk) is not bounded above or below.
متن کاملValues of the Euler function free of kth powers
We establish an asymptotic formula for the number of positive integers n x for which φ(n) is free of kth powers. © 2006 Elsevier Inc. All rights reserved. MSC: 11N37; 11A25
متن کاملSimultaneous Inequalities among Values of the Euler Φ-function
This paper concerns the values of the Euler φ-function evaluated simultaneously on corresponding members of k arithmetic progressions a1n + b1, a2n + b2, . . . , akn + bk. Assuming the necessary condition that no two of the polynomials aix + bi are constant multiples of each other, we show that for any positive constant C, there are infinitely many integers n for which simultaneously φ(a1n + b1...
