SPARSE FOURIER TRANSFORM VIA BUTTERFLY ALGORITHM
Fourier transform butterfly algorithm multiscale methods far field pattern
2015/7/14
This paper introduces a fast algorithm for computing sparse Fourier transforms with spatial and Fourier data supported on curves or surfaces. This problem appears naturally in several important applic...
The fast Fourier Transform and fast Wavelet Transform for Patterns on the Torus
wavelets lattices multivariate fast Fourier transform periodic multiresolution analysis Dirichlet wavelets
2011/9/21
Abstract: We introduce a fast Fourier Transform on regular d-dimensional lattices. We investigate properties of congruence class representants, i.e. their ordering, to classify directions and derive a...
Analysis of a Fast Fourier Transform Based Method for Modeling of Heterogeneous Materials
Homogenization Fast Fourier Transform Conjugate Gradients
2011/9/20
Abstract: The focus of this paper is on the analysis of the Conjugate Gradient method applied to a non-symmetric system of linear equations, arising from a Fast Fourier Transform-based homogenization ...
Generalized Fourier transform on Chébli-Triméche hypergroups
Ch´ ebli-Trim`eche hypergroups Generalized Fourier transform
2011/3/1
In this paper, we prove the Hardy-Littlewood inequality for the generalized Fourier transform on Ch´ebli-Trim`eche hypergroups and we study in the particular case of the Jacobi hypergroup the in...
We calculate the local Fourier transforms for connections on the formal punctured disk, corroborating the results of J. Fang and C. Sabbah using a different method. Our method is similar to Fang's, bu...
The discrete Fourier transform of $r$-even functions
periodic function multiplicative function r-even function discrete Fourier transform
2010/12/14
We give a detailed study of the discrete Fourier transform (DFT) of r-even arithmetic unctions,
which form a subspace of the space of r-periodic arithmetic functions. We consider the DFT of
sequence...
Estimate of the $L^p$-Fourier Transform Norm on Strong *-Regular Exponential Solvable Lie Groups
Exponential Lie group Plancherel measure unitary representation coadjoint orbit $L^p$-Fourier transform
2007/12/13
We study the $L^{p}$-Fourier transform for a special class of exponential Lie groups, the strong $\ast$-regular exponential Lie groups. Moreover, we provide an estimate of its norm using the orbit met...

Estimates for Fourier Transform of Measures Supported on Singular Hypersurfaces
Oscillatory Integrals oscillation index singular hypersurfaces curvature
2010/2/26
We consider hypersurfaces S \subset \RR3 with zero Gaussian curvature at every ordinary point with surface measure dS and define the surface measure dm = y(x)dS(x) for smooth function y with compact s...
