Real Linear-Metric Space and Isometric Functions
Let V be a non empty metric structure. We say that V is convex if and only if the condition (Def. 1) is satisfied. (Def. 1) Let x, y be elements of the carrier of V and r be a real number. Suppose 0 ¬ r and r ¬ 1. Then there exists an element z of the carrier of V such that ρ(x, z) = r · ρ(x, y) and ρ(z, y) = (1 − r) · ρ(x, y). Let V be a non empty metric structure. We say that V is internal if...
متن کاملThick metric spaces , relative hyperbolicity , and quasi - isometric rigidity
We study the geometry of non-relatively hyperbolic groups. Generalizing a result of Schwartz, any quasi-isometric image of a non-relatively hyperbolic space in a relatively hyperbolic space is contained in a bounded neighborhood of a single peripheral subgroup. This implies that a group being relatively hyperbolic with non-relatively hyperbolic peripheral subgroups is a quasi-isometry invariant...
متن کاملINTUITIONISTIC FUZZY QUASI-METRIC AND PSEUDO-METRIC SPACES
In this paper, we propose a new definition of intuitionistic fuzzyquasi-metric and pseudo-metric spaces based on intuitionistic fuzzy points. Weprove some properties of intuitionistic fuzzy quasi- metric and pseudo-metricspaces, and show that every intuitionistic fuzzy pseudo-metric space is intuitionisticfuzzy regular and intuitionistic fuzzy completely normal and henceintuitionistic fuzzy nor...
متن کاملQuasi-metric and Metric Spaces
We give a short review of a construction of Frink to obtain a metric space from a quasi-metric space. By an example we illustrate the limits of the
متن کاملFixed Point Theorems on Complete Quasi Metric Spaces Via C-class and A-Class Functions
In this paper, we present some fixed point theorems for single valued mappings on $K$-complete, $M$-complete and Symth complete quasi metric spaces. Here, for contractive condition, we consider some altering distance functions together with functions belonging to $C$-class and $A$-class. At the same time, we will consider two different type $M$ functions in contractive conditions because the qu...
