چکیده

We prove some extension theorems involving uniformly continuous maps of the universal Urysohn space. As an application, we prove reconstruction theorems for certain groups of autohomeomorphisms of this space and of its open subsets.

2 00 5 Extension theorems and reconstruction theorems for the Urysohn Universal Space

Such a space is unique up to isometry. We shall investigate group LIP(U) of bilipschitz homeomorphisms of U and some related groups. Indeed, the group H(U) of all homeomorphisms of U comes to mind first. However, by V. Uspenskiy [Us], U is homeomorphic to l2. So H(U) is in fact the group of homeomomorphisms of a Banach space, and can be better understood as such. For LIP(U) and for other groups...

Random and Universal Metric Spaces

We introduce a model of the set of all Polish (=separable complete metric) spaces: the cone R of distance matrices, and consider geometric and probabilistic problems connected with this object. The notion of the universal distance matrix is defined and we proved that the set of such matrices is everywhere dense Gδ set in weak topology in the cone R. Universality of distance matrix is the necess...

Random Metric Spaces and the Universal Urysohn Space.2

We introduce a model of the set of all Polish (=separable complete metric) spaces which is the cone R of distance matrices, and consider the geometrical and probabilistic problems connected with this object. We prove that the generic Polish space in the sense of this model is the so called universal Urysohn space which was defined by P.S.Urysohn in the 1920-th. Then we consider the metric space...

$C$-class and $F(psi,varphi)$-contractions on $M$-metric spaces

Partial metric spaces were introduced by Matthews in 1994 as a part of the study of denotational semantics of data flow networks. In 2014 Asadi and {it et al.} [New Extension of $p$-Metric Spaces with Some fixed point Results on $M$-metric paces, J. Ineq. Appl. 2014 (2014): 18] extend the Partial metric spaces to $M$-metric spaces. In this work, we introduce the class of $F(psi,varphi)$-contrac...

Ramsey–milman Phenomenon, Urysohn Metric Spaces, and Extremely Amenable Groups

In this paper we further study links between concentration of measure in topological transformation groups, existence of fixed points, and Ramsey-type theorems for metric spaces. We prove that whenever the group Iso (U) of isometries of Urysohn’s universal complete separable metric space U, equipped with the compact-open topology, acts upon an arbitrary compact space, it has a fixed point. The ...
