The Applied and Numerical Harmonic Analysis (ANHA) book series aims to provide the
engineering, mathematical, and scientific communities with significant developments in …

NFFT 3 is a software library that implements the nonequispaced fast Fourier transform
(NFFT) and a number of related algorithms, for example, nonequispaced fast Fourier …

The evolution of many microbes and pathogens, including circulating viruses such as
seasonal influenza, is driven by immune pressure from the host population. In turn, the …

Recently, the class of Generalized Locally Toeplitz (GLT) sequences has been introduced
as a generalization both of classical Toeplitz sequences and of variable coefficient …

Kernel-based methods are heavily used in machine learning. However, they suffer from
complexity in the number of considered data points. In this paper, we propose an …

We introduce a new class of multilevel, adaptive, dual‐space methods for computing fast
convolutional transformations. These methods can be applied to a broad class of kernels …

Based on a parallel scalable library for Coulomb interactions in particle systems, a
comparison between the fast multipole method (FMM), multigrid-based methods, fast Fourier …

We consider the numerical solution of the discrete multi-marginal optimal transport (MOT) by
means of the Sinkhorn algorithm. In general, the Sinkhorn algorithm suffers from the curse of …

We consider the fast Fourier transform at nonequispaced nodes (NFFT), and give detailed
information on the time and memory requirements of its building blocks. This manuscript …

Motivated by a recent halftoning method which is based on electrostatic principles, we
analyze a halftoning framework where one minimizes a functional consisting of the …
