WebMay 30, 2024 · The fixed point is unstable (some perturbations grow exponentially) if at least one of the eigenvalues has a positive real part. 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. 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. I have not succeeded in feeding a modified objective function to one of …

11.1: Fixed Points and Stability - Mathematics LibreTexts

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. Then a prefixed point (also spelled pre-fixed point, sometimes shortened to prefixpoint or pre … See more In mathematical logic, fixed-point logics are extensions of classical predicate logic that have been introduced to express recursion. Their development has been motivated by See more A topological space $${\displaystyle X}$$ is said to have the fixed point property (FPP) if for any continuous function See more In combinatory logic for computer science, a fixed-point combinator is a higher-order function $${\displaystyle {\textsf {fix}}}$$ that returns a fixed point of its argument function, if one exists. Formally, if the function f has one or more fixed points, then See more A fixed-point theorem is a result saying that at least one fixed point exists, under some general condition.
