Fixed points
WebFixed-point theorems are very useful for finding out if an equation has a solution. For example, in differential equations, a transformation called a differential operator … WebA 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.

Show that if X is compact and all fixed points of X are Lefschetz, then f has only finitely many fixed points. n.b. Let f: X → X. We say x is a fixed point of f if f ( x) = x. If 1 is not an eigenvalue of d f x: T X x → T X x, we say x is a Lefschetz fixed point. I have proved that x is a Lefschetz fixed point of f if and ...

WebA 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" to the fixed point.
