WebThe Schauder fixed-point theorem is an extension of the Brouwer fixed-point theorem to topological vector spaces, which may be of infinite dimension.It asserts that if is a nonempty convex closed subset of a Hausdorff topological vector space and is a continuous mapping of into itself such that () is contained in a compact subset of , then has a fixed point.

Break-Even Analysis: How to Calculate the Break-Even Point
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 See more In combinatory logic for computer science, a fixed-point combinator is a higher-order function $${\displaystyle {\textsf {fix}}}$$ that returns a fixed … 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 mathematical logic, fixed-point logics are extensions of classical predicate logic that have been introduced to express recursion.

Some examples follow. • In projective geometry, a fixed point of a projectivity has been called a double point. • In See more Webfixed-point: [adjective] involving or being a mathematical notation (as in a decimal system) in which the point separating whole numbers and fractions is fixed — compare floating … Web1 Answer. Given an ODE x ′ = f ( x). A fixed point is a point where x ′ = 0. 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 ... cid net worth
