The Quadfurcation

Quadfurcation is a bifurcation when four fixed points are created from none at a single location in phase space upon variation of one parameter. This bifurcation is not at all well studied in dynamical systems literature. In this paper Bäcker and Meiss put forth that the quadfurcation is an organizing center for the dynamics of a four-dimensional map, the quadratic diffeomorphism introduced by Moser in 1994.

Spatio-Temporal Patterns of Rioting Activity: A Reaction-Diffusion Approach

Berestycki, Nadal, and Rodríguez introduced and analyzed some systems of partial differential equations that serve as basic models for the spread of rioting activity. 

Red Sock Awards Awarded to Best Snowbird Posters
