Ultrametrics, Banach's fixed point theorem and the Riordan group
We interpret the reciprocation process in K[[x]] as a fixed point problem related to contractive functions for certain adequate ultrametric spaces. This allows us to give a dynamical interpretation of certain arithmetical triangles introduced herein. Later we recognize, as a special case of our construction, the so called Riordan group which is a device used in combinatorics. In this manner we ...
متن کاملTransversal spaces and common fixed point Theorem
In this paper we formulate and prove some xed and common xed pointTheorems for self-mappings dened on complete lower Transversal functionalprobabilistic spaces.
متن کامل$S$-metric and fixed point theorem
In this paper, we prove a general fixed point theorem in $textrm{S}$-metric spaces for maps satisfying an implicit relation on complete metric spaces. As applications, we get many analogues of fixed point theorems in metric spaces for $textrm{S}$-metric spaces.
متن کاملThe Fundamental Group and Brouwer’s Fixed Point Theorem
The fundamental group is an invariant of topological spaces that measures the contractibility of loops. This project studies the fundamental group, its basic properties, some elementary computations, and a resulting theorem: the Fixed Point Theorem of Brouwer, which states that every continuous function mapping the disk to itself has a fixed point.
