Regularization, renormalization, and renormalization groups

open access: yes, 2011
This paper confronts renormalization used in quantum field theory and that used in critical phenomena studies in statistical mechanics or dynamical systems theory. Regularization that cures spurious divergences is distinguished from renormalization transformations allowing to compute actual physical divergences.

Self-similar decay to the marginally stable ground state in a model for film flow over inclined wavy bottoms

open access: yesElectronic Journal of Differential Equations, 2012
The integral boundary layer system (IBL) with spatially periodic coefficients arises as a long wave approximation for the flow of a viscous incompressible fluid down a wavy inclined plane. The Nusselt-like stationary solution of the IBL is linearly at
