Originální abstrakt
We introduce a concept of neighborhood operator on a category. Such an operator is obtained by assigning to every atom of the subobject lattice of a given object a centered stack of subobjects of the object subject to two axioms. We study separation, compactness and convergence defined in a natural way by the help of a neighborhood operator. We show that they behave analogously to the separation, compactness and convergence in topological spaces. We also investigate relationships between the separation and compactness as defined on one hand and those with respect to the closure operator induced by the neighborhood operator considered on the other hand.
Český abstrakt
V práci je definován pojem operátoru okolí na kategorii. Tento operátor je obdržen tak, že každému atomu podobjektového svazu daného objektu je přiřazen centrovaný stack podobjektů tohoto objektu při splnění jistých axiomů. Je studována separovanost, kompaktnost a konvergence, které jsou definovány přirozeným způsobem pomocí operátora okolí.
