Nonsmooth Homoclinic Bifurcation in a Conceptual Climate Model
Julie Leifeld
Collision of equilibria with a splitting manifold has been locally studied, but might also be a contributing factor to global bifurcations. In particular a boundary collision can b…

Perturbation of a Nonsmooth Supercritical Hopf Bifurcation
Julie Leifeld
Nonsmooth formulations of physical models are common, particularly in climate modeling. However, in many of these models, there is little justification for this modeling choice, an…

Persistence of Saddle Behavior in the Nonsmooth Limit of Smooth Dynamical Systems
Julie Leifeld, Kaitlin Hill, Andrew Roberts
Models such as those involving abrupt changes in the Earth's reflectivity due to ice melt and formation often use nonlinear terms (e.g., hyperbolic tangent) to model the transition…
