2017-12-19 • Construct ODE (Ordinary Differential Equation) models • Relationship between the diagram and the equations • Alter models to include other factors. Simple epidemics Solve directly equations Solution over time Phase-portrait (picture) Tmes implct Equilibria (ODEs = 0) Stability of equilibria This simple diagram tells you roughly how the system behaves. It’s called the phase line. The phase line captures exactly the information we use to get the qualitative sketch of solution curves. We illustrate this with some examples.

Sometimes we can create a little diagram known as a Phase Line that gives us information regarding the nature of solutions to a differential equation.. We have already seen from the Stable, Semi-Stable, and Unstable Equilibrium Solutions page that we can determine whether arbitrary solutions to a differential equation converge on both sides to an equilibrium solution (which we An equilibrium of such an equation is a value of x for which F (x) = 0 (because if F (x) = 0 then x ' (t) = 0, so that the value of x does not change). A phase diagram indicates the sign of x ' (t) for a representative collection of values of x. To construct such a diagram, plot the function F, which gives the value of x '. 2015-02-24 · Phase line diagram are used to visualize the solution of the differential equation in one dimensional diagram.

This is the substantially revised and restructured second edition of Ron Shone's successful undergraduate and gradute textbook Economic Dynamics. The book provides a detailed coverage of dynamics and phase diagrams including: quantitative and qualitative dynamic systems, continuous and discrete dynamics, linear and nonlinear systems and single equation and systems of equations.

It is easier to just look at the phase diagram or phase portrait, which is a simple way to visualize the behavior of autonomous equations. In this case there is one dependent variable \(x\). We draw the \(x\) axis, we mark all the critical points, and then we draw arrows in between.
