gradient system
A gradient system in is an autonomous ordinary differential equation
(1) |
defined by the gradient of where and . The following results can be deduced from the definition of a gradient system.
Properties:
-
•
The eigenvalues of the linearization of (1) evaluated at equilibrium point are real.
-
•
If is an isolated minimum of then is an asymptotically stable solution of (1)
-
•
If is a solution of (1) that is not an equilibrium point then is a strictly decreasing function and is perpendicular to the level curves of .
-
•
There does not exists periodic solutions of (1).
