WebFixed-point theorem. In mathematics, a fixed-point theorem is a result saying that a function F will have at least one fixed point (a point x for which F ( x) = x ), under some conditions on F that can be stated in general terms. [1] Some authors claim that results of this kind are amongst the most generally useful in mathematics. WebQuestion: definition: Let f : S → S. The point x0 ∈ S is a fixed point (of f) if f(x0) = x0. Prove the following when S = [a, b] with a < b: (a) If f(x) is continuous then f(x) has at least one fixed point. (b) If f(x) is differentiable with f 0 (x) > 1 on S then f(x) has exactly 1 fixed point. (c) Show that f 0 (x) > 1 is sharp.
