Noun1.metric space - a set of points such that for every pair of points there is a nonnegative real number called their distance that is symmetric and satisfies the triangle inequality

The research paper introduces homology and cohomology with real coefficients which reflect the metric properties of the underlying compact metric spaces, focusing on a category of pairs of compact metric spaces and Lipschitz maps where the pairs satisfy a linearly isoperimetric condition related to the solvability of the Plateau problem with partially free boundary.
The preceding scaling limit holds for the Gromov-Hausdorff distance on compact metric spaces.
In this paper we are interested in metric spaces whose free space is isometric to (a subspace of) [l.
generalize the result of Branciari in ordinary metric spaces.
There have been a number of generalizations of metric spaces such as vector valued metric spaces, G-metric spaces, pseudometric spaces, fuzzy metric spaces, D-metric spaces, cone metric spaces, and modular metric spaces.

Ozavsar and Cevikel [16] investigated the multiplicative metric spaces along with its topo-logical properties, few of them are given below:
infinity]](p) and c(p) fail to be linear metric spaces because the continuity of scalar multiplication does not hold for them but these two turn out to be linear metric spaces if and only if [inf.
The underlying geometric objects in this new context will not be metric spaces, but diversities, a generalization of metrics recently introduced by Bryant and Tupper [4].
