The variety ddpM of de Morgan algebras with double demi-pseudocomplementation consists of those algebras (L; ∧ , ∨ , , , + , 0, 1) of type (2, 2, 1, 1, 1, 0, 0) where (L; ∧ , ∨ , , 0, 1) is a de Morgan algebra, (L; ∧ , ∨ , , + , 0, 1) is a double demi-p-lattice and the operations x → x , x → x and x → x + are linked by the identities x = x , x + = x + and x + = x + . In this paper, we characterize congruences on a ddpM-algebra, and give a description of the subdirectly irreducible algebras.

In this article a recently proposed method called the particle mesh Ewald (PME) method for computing the long ranged Coulomb interactions in for example molecular dynamics simulations is studied. The PME method has a complexity O(N log N), where N is the total number of charges. This complexity should in particular be compared with the complexity O(N-3/2) for the well known Ewald method and O(N) for the rather new (but already famous) fast multipole method (FMM). However, these complexities say nothing about which method is fastest at some finite N. The purpose of this article is thus to study the PME method and compare its efficiency with the Ewald method and the fast multipole method. To enable this, a theoretical estimate for the accuracy of the PME method as function of its truncation parameters is derived. It is shown that this estimate is very precise by comparing it with results obtained from molecular dynamics simulations of a molten NaCl. Based on this estimate and very careful time experiments, the overall necessary time overhead for the PME method as function of N and a required accuracy is predicted. By a direct comparison with a similar prediction for the Ewald method and by studying existing Ewald-FMM comparisons, it is found that the PME method is significantly faster than both the Ewald method and the fast multipole method in the important decades N similar or equal to 10(4)-10(5).

A new n th-order Hankel transform (also called Fourier-Bessel transform) algorithm designed for analytically defined functions is presented. This algorithm is not restricted to order zero. As such, it provides greater generality than many found in the literature. The traditional difficulty in the evaluation of Hankel transforms, the presence of Bessel functions in the kernel of the integral transform, is eliminated in this new Hankel transform algorithm. The algorithm presented here is composed of a fast (linear time) n th-order Chebyshev transform followed by a fast Fourier transform.

Matrices of the form [C V] consisting of a generalized Cauchy matrix and a generalized Vandermonde matrix are considered. Using the displacement structure of these matrices, inversion formulas and criteria are presented. The interpretation of linear systems with such a coefficient matrix as tangential interpolation problems leads to the concept of fundamental matrix, which is basic in this approach. For fundamental matrices recursion formulas are established. From them, fast inversion algorithms emerge that work for arbitrary nonsingular matrices of this kind. (C) 1998 Elsevier science Inc.
