We prove that the topology induced by any (complete) fuzzy metric space (in the sense of George and Veeramani) is (completely) metrizable. We also show that every separable fuzzy metric space admits a precompact fuzzy metric and that a fuzzy metric space is compact if and only if it is precompact an

β¦ Synopsis
This paper deals with some properties of a new metric (here called "the Hausdor -Skorokhod metric") previously introduced by Joo and Kim on the space of fuzzy numbers in the Euclidean space R k . We ΓΏrst prove that convergence in the Hausdor -Skorokhod metric implies convergence in the sendograph metric. Also, we show that the Hausdor -Skorokhod metric is not absolutely homogeneous and not translation invariant, and investigate the continuity of operations and convexity on the space of fuzzy numbers equipped with the Hausdor -Skorokhod metric.

A necessary and sufficient condition for a fuzzy metric space to be complete is given. We prove that a subspace of a separable fuzzy metric space is separable and every separable fuzzy metric space is second countable. Uniform limit theorem is generalized to fuzzy metric spaces.
In this paper, by embedding the fuzzy number space with the sendograph metric into the product of two uniformly support bounded complete metric spaces, we characterize compact sets of the fuzzy number space. The main result is that with respect to the sendograph metric a closed set is compact if and
The space of Lorentz metrics on a compact manifold is very different from its Riemannian analogue. There are usually many connected components. We show that some of them turn out to be not simply connected. We also show that, in dimension greater than 2, the distance between two components is always
