Systems of ODEs - Saddle Points and Instability
Offered By: Steve Brunton via YouTube
Course Description
Overview
Explore the concept of unstable saddle points in 2-dimensional linear systems of ordinary differential equations. Delve into the characteristics of solutions with positive and negative real eigenvalues. Discover the practical applications of saddle points in energy-efficient transport, including bipedal walking, fighter jet maneuvers, and interplanetary travel. Examine solutions using eigenvalues, eigenvectors, and phase portrait visualizations. Learn how to draw saddles in phase space and study real-world examples such as human locomotion, particle behavior in potential wells, and planetary movement within the solar system.
