Journal ArticleDOI
A fast algorithm for particle simulations
TL;DR: An algorithm is presented for the rapid evaluation of the potential and force fields in systems involving large numbers of particles whose interactions are Coulombic or gravitational in nature, making it considerably more practical for large-scale problems encountered in plasma physics, fluid dynamics, molecular dynamics, and celestial mechanics.

The Rapid Evaluation of Potential Fields in Particle Systems
TL;DR: In this paper, an algorithm for the rapid evaluation of the potential and force fields in large-scale ensembles of particles is presented, which requires an amount of work proportional to the number of particles.
Journal ArticleDOI
A new version of the Fast Multipole Method for the Laplace equation in three dimensions
TL;DR: A new version of the Fast Multipole Method for the evaluation of potential fields in three dimensions is introduced based on a new diagonal form for translation operators and yields high accuracy at a reasonable cost.
Journal ArticleDOI
Accelerating the Nonuniform Fast Fourier Transform
Leslie Greengard,June-Yub Lee +1 more
TL;DR: This paper observes that one of the standard interpolation or "gridding" schemes, based on Gaussians, can be accelerated by a significant factor without precomputation and storage of the interpolation weights, of particular value in two- and three- dimensional settings.
Journal ArticleDOI
Regular Article: A Fast Adaptive Multipole Algorithm in Three Dimensions
TL;DR: An adaptive fast multipole method for the Laplace equation in three dimensions that uses both new compression techniques and diagonal forms for translation operators to achieve high accuracy at a reasonable cost.
