Topological monoids of monotone injective partial selfmaps of ▫$\mathbb{N}$▫ with cofinite domain and imageGutik, Oleg ; Repovš, Dušan, 1954-V članku preučujemo polgrupo ▫${\mathscr I}_\infty^\nearrow(\mathbb{N})$▫ parcialnih kofinalnih monotonih bijektivnih transformacij množice pozitivnih celih števil ▫$\mathbb{N}$▫. Dokažemo, da ima ... polgrupa ▫${\mathscr I}_\infty^\nearrow(\mathbb{N})$▫ podobne algebrske lastnosti kot biciklična polgrupa: je bienostavna in vsi njeni netrivialni grupni homomorfizmi so bodisi izomorfizmi bodisi grupni homomorfizmi. Dokažemo tudi, da je vsaka lokalno kompaktna topologija ▫$\tau$▫ on ▫${\mathscr I}_\infty^\nearrow(\mathbb{N})$▫, za katero je ▫$({\mathscr I}_\infty^\nearrow(\mathbb{N}), \tau)$▫ topološka inverzna polgrupa, diskretna. Na koncu še opišemo zaprtje ▫$({\mathscr I}_\infty^\nearrow(\mathbb{N}), \tau)$▫ v topološki polgrupi.Source: Studia scientiarum mathematicarum Hungarica. - ISSN 0081-6906 (Vol. 48, no. 3, 2011, str. 342-353)Type of material - article, component partPublish date - 2011Language - englishCOBISS.SI-ID - 15968089
