Propagation of fronts in the Fisher-Kolmogorov equation with spatially varying diffusion

Christopher W. Curtis, David M. Bortz

The propagation of fronts in the Fisher-Kolmogorov equation with spatially varying diffusion coefficients is studied. Using coordinate changes, WKB approximations, and multiple sca…

Eigenvalues for Two-Lag Linear Delay Differential Equations

David Bortz

We consider the class of two-lag linear delay differential equations and develop a series expansion to solve for the roots of the nonlinear characteristic equation. Supporting nume…
