Pellicer–Covarrubias, Cells in hyperspaces, Topology Appl. Two spaces with a homeomorphism between them are called homeomorphic, and from a topological viewpoint they are the same. It is the purpose of this paper to use Norden's technique to show that Pixley-Roy hyperspaces of infinite, as well as finite, graphs are all the same. Pellicer, The hyperspaces C ( p, X ), Topol. Homeomorphisms are the isomorphisms in the category of topological spacesthat is, they are the mappings that preserve all the topological properties of a given space. It follows that the Pixley- Roy hyperspaces of spaces like R, 0,1, and the circle are all homeomorphic.

We also want to thank Professors Fernando Macías Romero and David Herrera Carrasco for asking the questions wich motivated us to write down this paper. Moreover, we introduce a new class of homeomorphism called - Homeomorphism, which are weaker than homeomorphism. The authors wish to thank Eli Vanney Roblero and Rosemberg Toalá for the fruitful discussions. In this paper, we first introduce a new class of closed map called -closed map. Furthermore, in the continuous complete case, the d_H-Scott topology coincides with the lower Vietoris topology, and the d_Q-Scott topology coincides with the upper Vietoris topology.Acknowledgments. Then we show that the Hoare and Smyth powerdomains of an algebraic complete quasi-metric space are again algebraic complete, with those quasi-metrics, and similarly that the corresponding powerdomains of continuous complete quasi-metric spaces are continuous complete. Through these isomorphisms again, the two powerdomains inherit quasi-metrics d_H and d_Q, respectively, that are reminiscent of the well-known Hausdorff metric. Turning to the corresponding hyperspaces, namely the same powerdomains, but equipped with the lower Vietoris and upper Vietoris topologies instead, this turns into homeomorphisms with the corresponding space of previsions, equipped with the so-called weak topology. There are natural isomorphisms between the Hoare and Smyth powerdomains, as used in denotational semantics, and spaces of discrete sublinear previsions, and of discrete normalized superlinear previsions, respectively. Periodic points of rational area-preserving homeomorphisms. but it can not be exact because it is an homeomorphism. We show that the Kantorovich-Rubinstein quasi-metrics d_KR and d^a_KR of Part I extend naturally to various spaces of previsions, and in particular not just the linear previsions (roughly, measures) of Part I. induced dynamics on the hyperspaces are chain transitive, or none of them is.
