systems of first-order linear autonomous differential equations. Given a square matrix A, we say that a non-zero vector c is an eigenvector of A with eigenvalue l if Ac = lc.
2014-04-11 · Chapter & Page: 43–2 Nonlinear Autonomous Systems of Differential Equations To find the criticalpoints, we need to find every orderedpairof realnumbers (x, y) at which both x ′and y are zero. This means algebraically solving the system 0 = 10x − 5xy 0 = 3y + xy − 3y2. (43.2) Fortunately, the first equation factors easily:

When the variable is time, they are also called time-invariant systems. A differential equation is called autonomous if it can be written as \ [ \dfrac {dy} {dt} = f (y). All autonomous differential equations are characterized by this lack of dependence on the independent variable. Many systems, like populations, can be modeled by autonomous differential equations. These systems grow and shrink independently—based only on their own behavior and not by any external factors. A system of ordinary differential equations which does not explicitly contain the independent variable t (time). The general form of a first-order autonomous system in normal form is: x ˙ j = f j (x 1 … x n), j = 1 … n, or, in vector notation, These are the standard properties of the systems of autonomous equations.
0 … autonomous equations. These have the form dy dt = g(y). (3.1) Here the derivative of y with respect to t is given by a function g(y) that is independent of t. 3.1.1. Recipe for Solving Autonomous Equations. Just as we did for the linear case, we will reduce the autonomous case to the explicit case. The trick to doing this is to consider t to be systems of first-order linear autonomous differential equations.
