Chapter 9.2, Problem 1E
Interpretation Introduction

Interpretation:

To show that for the Lorenz equations, the characteristic equation for the eigenvalues of the Jacobian matrix at C+, C is λ3 + (σ + b + 1)λ2 + (r + σ) bλ + 2bσ(r - 1) = 0. To show that there is a pair of pure imaginary eigenvalues when r = rH = σ (σ + b + 3)(σ - b - 1) for the solutions of the form λ = iω, where ω is real. To explain why we need to assume σ > b + 1. To find the third eigenvalue.

Concept Introduction:

The Jacobian matrix is given by:

A = (x˙xx˙yx˙zy˙xy˙yy˙zz˙xz˙yz˙z)

The Eigen value λ can be calculated using the characteristic equation

|(A - λI)| = 0
