Shock-layer bounds for a singularly perturbed equation [PDF]
The size of the shock-layer governed by a conservation law is studied. The conservation law is a parabolic reaction-convection-diffusion equation with a small parameter multiplying the diffusion term and convex flux.

Scaling Exponents of Turbulent Static Pressure Structure Function in the Inertial Subrange
Abstract The measured variations in the turbulent static pressure structure function Dpp(r) ${D}_{pp}(r)$ with scale r $r$ in the roughness sublayer above a subarctic forest are empirically shown to exhibit exponents that are smaller than r4/3 ${r}^{4/3}$ predicted for the inertial subrange (ISR).

In this paper, we present an analysis of overlapping Schwarz method for singularly perturbed third order reaction-diffusion problems. The Schwarz method invokes two fine mesh subdomains and one coarse mesh subdomain.

Singularly perturbed equations of degenerate type
This work is devoted to the study of nonvariational, singularly perturbed elliptic equations of degenerate type. The governing operator is anisotropic and ellipticity degenerates along the set of critical points. The singular behavior is of order \text{O}\left(\frac{1}{\epsilon }\right)

A numerical approach for investigating a special class of fractional Riccati equation
A computational scheme for solving special type of fractional Riccati equation with singularly perturbed (FRSP) is investigated. It is based on dividing the equation into algebraic equation and fractional equation.
