 Section Mathematics Title Dynamical system of translations in the space of multi-valued functions with closed images Author(-s) Panasenko E.A.a Affiliations Tambov State Universitya Abstract In the work there is considered the dynamical system of translations in the space ${\mathfrak R}$ of continuous multi-valued functions with images in complete metric space $\big({\rm clos}({\mathbb R}^n), \rho_{{\rm cl}}\big)$ of nonempty closed subsets of ${\mathbb R}^n.$ The distance between such functions is measured by means of the metric analogous to the Bebutov metric constructed for the space of continuous real-valued functions defined on the whole real line. It is shown that for compactness of the trajectory's closure in ${\mathfrak R}$ it is sufficient to have initial function bounded and uniformly continuous in the $\rho_{{\rm cl}}$ metric. As consequence, it is also proved that the trajectory's closure of a recurrent or an almost periodic motion is compact in ${\mathfrak R}.$ Keywords space of multivalued functions with closed images, dynamical system of translations, closure of trajectory UDC 517.938.5, 517.911.5 MSC 37С99, 34A60 DOI 10.20537/vm120203 Received 27 December 2011 Language Russian Citation Panasenko E.A.
