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 mapped to itself by the function. In physics, the term fixed point can refer to a … 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 fixed-point subgroup $${\displaystyle G^{f}}$$ of … See more A topological space $${\displaystyle X}$$ is said to have the fixed point property (FPP) if for any continuous function $${\displaystyle f\colon X\to X}$$ there exists $${\displaystyle x\in X}$$ such that $${\displaystyle f(x)=x}$$. The FPP is a See more In mathematical logic, fixed-point logics are extensions of classical predicate logic that have been introduced to express recursion. Their … See more A fixed-point theorem is a result saying that at least one fixed point exists, under some general condition. Some authors claim that results of this kind are amongst the most generally useful in mathematics. 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 … 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 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 See more WebThe main article fixed point arithemetic is a confused presentation of binary based fixed point stuff; the examples in the section Current common uses of fixed-point arithmetic …

Fixed-point Definition & Meaning - Merriam-Webster
WebA Gaussian fixed point is a fixed point of the renormalization group flow which is noninteracting in the sense that it is described by a free field theory. [1] The word Gaussian comes from the fact that the probability distribution is Gaussian at the Gaussian fixed point. This means that Gaussian fixed points are exactly solvable ( trivially ...
