... Since c0 is positive, the quantity under the square root is either smaller than c21 , or it is negative. If negative, the solutions are complex with real part −c1 , which is negative. Otherwise, the square root must be smaller in absolute value than c1 , so that the two eigenvalues must still be neg ...

Dynamical system
In mathematics, a dynamical system is a set of relationships among two or more measurable quantities, in which a fixed rule describes how the quantities evolve over time in response to their own values. Examples include the mathematical models that describe the swinging of a clock pendulum, the flow of water in a pipe, and the number of fish each springtime in a lake.At any given time a dynamical system has a state given by a set of real numbers (a vector) that can be represented by a point in an appropriate state space (a geometrical manifold). The evolution rule of the dynamical system is a function that describes what future states follow from the current state. Often the function is deterministic; in other words, for a given time interval only one future state follows from the current state; however, some systems are stochastic, in that random events also affect the evolution of the state variables.
