When applied to … WebMar 14, 2024 · The fixed-point technique has been used by some mathematicians to find analytical and numerical solutions to Fredholm integral equations; for example, see [1,2,3,4,5]. It is noteworthy that Banach’s contraction theorem (BCT) [ 6 ] was the first discovery in mathematics to initiate the study of fixed points (FPs) for mapping under a …
WebBrouwer's fixed-point theorem is a fixed-point theorem in topology, named after L. E. J. (Bertus) Brouwer. It states that for any continuous function mapping a compact convex set to itself there is a point such that . The simplest forms of Brouwer's theorem are for continuous functions from a closed interval in the real numbers to itself or ...
