Fixed points
In many fields, equilibria or stability are fundamental concepts that can be described in terms of fixed points. Some examples follow. In projective geometry, a fixed point of a projectivity has been called a double point. In economics, a Nash equilibrium of a game is a fixed point of the game's best response … See more A fixed point (sometimes shortened to fixpoint, also known as an invariant point) is a value that does not change under a given transformation. Specifically, in mathematics, a fixed point of a function is an element that is … See more In algebra, for a group G acting on a set X with a group action $${\displaystyle \cdot }$$, x in X is said to be a fixed point of g if $${\displaystyle g\cdot x=x}$$. The See more In domain theory, the notion and terminology of fixed points is generalized to a partial order. Let ≤ be a partial order over a set X and let f: X → X be a function over X.

WebMar 4, 2013 · The mathematically correct way of doing a fit with fixed points is to use Lagrange multipliers. Basically, you modify the objective function you want to minimize, which is normally the sum of squares of the residuals, adding an extra parameter for every fixed point.

In domain theory, the notion and terminology of fixed points is generalized to a partial order. 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. Malkis justifies the definition presented here as follows: "since f is before …
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.
