Fixed points can be further classified as stable or unstable nodes, unstable saddle points, stable or unstable spiral points, or stable or unstable improper nodes.
WebDiscrete fixed-point theorem. In discrete mathematics, a discrete fixed-point is a fixed-point for functions defined on finite sets, typically subsets of the integer grid . Discrete fixed-point theorems were developed by Iimura, [1] Murota and Tamura, [2] Chen and Deng [3] and others. Yang [4] provides a survey.

This requires f ( x) = 0. So any roots of the function f ( x) is a fixed point. A fixed point is stable if, roughly speaking, if you put in an initial value that is "close" to the fixed point the trajectory of the solution, under the ODE, will always stay "close" to the fixed point.

Let ≤ be a partial order over a set X and let f: X → X be a function over X. Then a prefixed point (also spelled pre-fixed point, sometimes shortened to prefixpoint or pre-fixpoint) of f is any p such that f(p) ≤ p. Analogously, a postfixed point of f is any p such that p ≤ f(p). The opposite usage occasionally appears.
