Abstract. pde2path 2.4 is a continuation/bifurcation package for systems of PDEs over bounded d-dimensional domains, d=1,2,3, including features such as nonlinear boundary conditions, cylinder and torus geometries (i.e., periodic boundary conditions), and a general interface for adding auxiliary equations like mass conservation or phase equations for continuation of traveling waves. The original version 1.0 was for elliptic systems in 2D and based on the Matlab pdetoolbox, which since v2.3 has been more or less replaced by the free package OOPDE. Recent additions (v2.4) include the handling of multiple steady bifurcation points, Branch point continuation and Hopf point continuation via extended systems, continuation of relative equilibria (e.g., traveling waves and rotating waves), and branch switching from periodic orbits (Hopf pitchfork/transcritical bifurcation, and period doubling).
