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

A new Legendre wavelets decomposition method for solving PDEs
Malaya Journal of Matematik, 2014 In this paper, we present a novel technique based on the Legendre wavelets decomposition. The properties of Legendre wavelets are used to reduces the PDEs problem into the solution of ODEs system. To illustrate our results, two examples are studied using a special software package which implements the proposed algorithms.

Adaptive Spectral Galerkin Methods with Dynamic Marking [PDF]
, 2015 The convergence and optimality theory of adaptive Galerkin methods is almost exclusively based on the D\"orfler marking. This entails a fixed parameter and leads to a contraction constant bounded below away from zero.
