Two-dimensional Single-Variable Cubic Nonlinear Systems, Vol. I

Focusing on cubic nonlinear systems, this monograph introduces a systematic theory centered around single-variable vector fields. It delves into 1-dimensional flow singularities and bifurcations, showcasing previously unexplored bifurcations in 2-dimensional cubic systems. The text covers third-order source and sink flows, as well as parabola flows, highlighting the significance of infinite-equilibriums in switching bifurcations. Additionally, it details various bifurcations, including saddle flows and inflection flows, providing a comprehensive analysis of these complex systems.
