ODEs + dynamical systems¶
Five ranked references. Rank 1 is the default spine, not a requirement to read all five.
1 | Nonlinear Dynamics and Chaos¶
Steven H. Strogatz | Primary spine | Undergraduate / graduate
The best broad entry into phase lines, fixed points, oscillation, bifurcation, chaos, and qualitative modeling.
