This section examines the local behavior of nonlinear dynamical systems in the vicinity of hyperbolic equilibrium points. Using linearization and phase-plane analysis, the qualitative structure of phase portraits is studied, including the classification of equilibria and the corresponding trajectory patterns. The results illustrate how the local dynamics of nonlinear systems near hyperbolic equilibria can be inferred from their linear approximations, providing valuable insight into stability and system behavior.

This section introduces the phase plane as a graphical method for studying the qualitative behavior of dynamical systems. It presents the representation of system states, vector fields, and orbits, and outlines basic phase plane analysis techniques used to visualize system trajectories and assess dynamic behavior.

his section analyzes the qualitative behavior of linear second-order systems through their phase-plane representations. The different types of equilibrium points—such as nodes (nœuds), saddles, spirals, and centers—are introduced and classified according to the system eigenvalues. The associated trajectory patterns and stability properties are discussed, providing insight into how system parameters influence dynamic behavior and response characteristics.
