## Abstract We study the set __S__ = {(__a, b__) β __A__ Γ __A__ : __aba__ = __a, bab__ = __b__} which pairs the relatively regular elements of a Banach algebra __A__ with their pseudoinverses, and prove that it is an analytic submanifold of __A Γ A__. If __A__ is a C\*βalgebra, inside __S__ lies a

β¦ Synopsis
Let n>2 be an integer, and for each integer 0<a<n with (a, n)=1, define aΓ by the congruence aaΓ #1 (mod n) and 0<aΓ <n. The main purpose of this paper is to study the distribution behaviour of |a&aΓ |, and prove that for any fixed positive number 0<$ 1,
where ,(n) is the Euler function, and *[ } } } ] denotes the number of elements of the set
In this paper, we shall solve this problem, and give a sharp asymptotic formula. The constants implied by the O-symbols and the symbols R used in this paper do not depend on any parameter, unless otherwise indicated. By using estimates for Kloostermann sums and trigonometric sums, we prove the following: article no.

The inversive congruential method is an attractive alternative to the classical linear congruential method for pseudorandom number generation. The authors have recently introduced a new method for obtaining nontrivial upper bounds on the multidimensional discrepancy of inversive congruential pseudor
The purpose of this paper is to present some enumerative results concerning the class k of permutations of the multiset 1 m 1 2 m 2 r m r having inversion number congruent to k modulo n, with n = m 1 + m 2 + β’ β’ β’ + m r and 0 β€ k < n. We show that the enumeration of this family of permutations is co
