However we can, as V. I. Arnold V. I. Arnold and A. Avez, Ergodic problems in Classical Mechanics, Benjamin, New York, 1968 did, consider the picture of the cat on ?$N \times N$? raster. After a certain number of iterations the cat returns. We are interested in the dependence of the period of return on the density of the raster net. The property of return can be used for coding and covering up information</dc:description><dc:description xml:lang="sl">Hiperbolična matrika določa preslikavo na torusu, vendar jo lahko opazujemo tudi na ?$N \times N$? rastru, kot je to napravil V. I. Arnold V. I. Arnold in A. Avez, Ergodic problems in Classical Mechanics, Benjamin, New York, 1968. Opazoval je sliko mačke, ki se je po določenem številu iteracij vrnila. Zanima nas povezava med gostoto rastra in periodo vrnitve. To lastnost lahko uporabimo tudi za šifriranje in prikrivanje informacij</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:doc-MAND4T8M"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:doc-MAND4T8M" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:doc-MAND4T8M/ee2e94fb-fa54-4c82-b959-4bdefe55231d/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Društvo matematikov, fizikov in astronomov</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:doc-MAND4T8M/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:doc-MAND4T8M" /></ore:Aggregation></rdf:RDF>
