author keywords: numerical homogenization; wavelets; Helmholtz equation

TL;DR:
This work shows how to improve the efficiency of this numerical homogenization method by choosing a different compact representation of the homogenized operator, and suggests an approach for obtaining a sparse representation that is significantly simpler than the alternative sparse representations.

Self-similar intermediate asymptotics for a degenerate parabolic filtration-absorption equation

Contributors: G. Barenblatt, M. Bertsch ^{*}, ^{*} & V. Prostokishin ^{*}

MeSH headings : Geological Phenomena; Geology; Models, Biological; Models, Statistical; Models, Theoretical; Water

TL;DR:
Numerical experiments indicate that the self-similar solutions obtained represent intermediate asymptotics of a wider class of solutions when the influence of details of the initial conditions disappears but the solution is still far from the ultimate state: identical zero.
