Sekundarni naslov: | Induciranje funkcij med inverznimi limitami z navzgor polzveznimi veznimi funkcijami |
Sekundarni povzetek: | In this paper we introduce the category ▫$\mathcal{CU}$▫ in which the compact metric spaces are objects and upper semicontinuous functions from ▫$X$▫ to ▫$2^Y$▫ are morphisms from ▫$X$▫ to ▫$Y$▫. We also introduce the category ▫$\mathcal{ICU}$▫ of inverse sequences in ▫$\mathcal{CU}$▫. Then we investigate the induced functions between inverse limits of compact metric spaces with upper semicontinuous bonding functions. We provide criteria for their existence and prove that under suitable assumptions they have surjective graphs. We also show that taking such inverse limits is very close to being a functor (but is not a functor) from ▫$\mathcal{ICU}$▫ to ▫$\mathcal{CU}$▫, if morphisms are mapped to induced functions. At the end of the paper we give a useful application of the mentioned results. |
