ARKCoS: Artifact-Suppressed Accelerated Radial Kernel Convolution on the Sphere [PDF]
, 2011 We describe a hybrid Fourier/direct space convolution algorithm for compact radial (azimuthally symmetric) kernels on the sphere. For high resolution maps covering a large fraction of the sky, our implementation takes advantage of the inexpensive massive

Exact reconstruction with directional wavelets on the sphere [PDF]
, 2007 A new formalism is derived for the analysis and exact reconstruction of band-limited signals on the sphere with directional wavelets. It represents an evolution of the wavelet formalism developed by Antoine & Vandergheynst (1999) and Wiaux et al. (2005).

Estimates of Approximation Error by Legendre Wavelet
Applied Mathematics, 2016 This paper first introduces Legendre wavelet bases and derives their rich properties. Then these properties are applied to estimation of approximation error upper bounded in spaces and by norms and , respectively. These estimate results are valuable to solve integral-differential equations by Legendre wavelet method.

Modified Legendre Wavelets Technique for Fractional Oscillation Equations [PDF]
Entropy, 2015 Physical Phenomena’s located around us are primarily nonlinear in nature and their solutions are of highest significance for scientists and engineers. In order to have a better representation of these physical models, fractional calculus is used. Fractional order oscillation equations are included among these nonlinear phenomena’s.
