Nonlinear Problems in Fluid Dynamics and Inverse Scattering. Propagation and Capturing of Singularities in Problems of Fluid Dynamics and Inverse Scattering.

Abstract

Research investigations and development of the fast adaptive algorithms using orthonormal bases with controlled localization in the time- frequency domain (e.g. wavelets) have been successful and several new algorithms have been developed. Among the results is the Unequally Spaced Fast Fourier Transform (USFFT) algorithm and a new approach to numerical homogenization
