چکیده

We estimate exponential sums with the Fermat-like quotients fg(n) = gn−1 − 1 n and hg(n) = gn−1 − 1 P (n) , where g and n are positive integers, n is composite, and P (n) is the largest prime factor of n. Clearly, both fg(n) and hg(n) are integers if n is a Fermat pseudoprime to base g, and this is true for all g coprime to n when for any Carmichael number n. On the other hand, our bounds imply that the fractional parts {fg(n)} and {hg(n)} are uniformly distributed, on average over g for fg(n), and individually for hg(n).

The Pseudoprimes to 25 • 109

The odd composite n < 25 • 10 such that 2n_1 = 1 (mod n) have been determined and their distribution tabulated. We investigate the properties of three special types of pseudoprimes: Euler pseudoprimes, strong pseudoprimes, and Carmichael numbers. The theoretical upper bound and the heuristic lower bound due to Erdös for the counting function of the Carmichael numbers are both sharpened. Several...

On the Distributions of Pseudoprimes, Carmichael Numbers, and Strong Pseudoprimes

Building upon the work of Carl Pomerance and others, the central purpose of this discourse is to discuss the distribution of base-2 pseudoprimes, as well as improve upon Pomerance's conjecture regarding the Carmichael number counting function [8]. All conjectured formulas apply to any base b ≥ 2 for x ≥ x0(b). A table of base-2 pseudoprime, 2-strong pseudoprime, and Carmichael number counts up ...

The Distribution of Lucas and Elliptic Pseudoprimes

Let ¿?(x) denote the counting function for Lucas pseudoprimes, and 2?(x) denote the elliptic pseudoprime counting function. We prove that, for large x , 5?(x) < xL(x)~l/2 and W(x) < xL(x)~l/3 , where L(x) = exp(logxlogloglogx/log logx).

Notes on some new kinds of pseudoprimes

J. Browkin defined in his recent paper (Math. Comp. 73 (2004), pp. 1031–1037) some new kinds of pseudoprimes, called Sylow p-pseudoprimes and elementary Abelian p-pseudoprimes. He gave examples of strong pseudoprimes to many bases which are not Sylow p-pseudoprime to two bases only, where p = 2 or 3. In this paper, in contrast to Browkin’s examples, we give facts and examples which are unfavora...

Investigation of the role of fractional crystallization, crustal assimilation and magma mixing in turquoise hosted sub-volcanic intrusion rocks in south of Damghan mine, Iran.

Granodiorite and dioritic intrusive rocks (Middle Eocene age) intruded the Lower-Middle Eocene volcanic rocks at the northern parts of the Torud-Chah Shirin volcano-plutonic belt in north east of Iran. This granodiorite is intruded by small rhyolitic dome in the Damghan turquoise-gold mine. According to all data, these intrusive rocks are related to a common source. The primary magma evolved by...
