Journal ArticleDOI
On approximation of functions by exponential sums
Gregory Beylkin,Lucas Monzón +1 more
TL;DR: A new approach is introduced for the efficient approximation of functions and sequences by short linear combinations of exponential functions with complex-valued exponents and coefficients with significantly fewer terms than Fourier representations.
Journal ArticleDOI
Approximation by exponential sums revisited
Gregory Beylkin,Lucas Monzón +1 more
TL;DR: The efficient approximation of functions by sums of exponentials or Gaussians in Beylkin and Monzon (2005) is revisited to discuss several new results and applications, and the Poisson summation is used to discretize integral representations of e.g., power functions r − β, β > 0.
Journal ArticleDOI
On Generalized Gaussian Quadratures for Exponentials and Their Applications
Gregory Beylkin,Lucas Monzón +1 more
TL;DR: A generalization of a representation theorem due to Caratheodory is used to derive new families of Gaussian-type quadratures for weighted integrals of exponential functions and their applications to integration and interpolation of bandlimited functions.
Journal ArticleDOI
Fast convolution with the free space Helmholtz Green's function
TL;DR: An approximation of the free space Green's function for the Helmholtz equation is constructed that splits the application of this operator between the spatial and the Fourier domains, as in Ewald's method for evaluating lattice sums.
Journal ArticleDOI
Compactly Supported Wavelets Based on Almost Interpolating and Nearly Linear Phase Filters (Coiflets)
TL;DR: In this article, a compactly supported wavelet for which both the scaling and wavelet functions have a high number of vanishing moments is presented, which is useful in applications where interpolation and linear phase are of importance.
