| Abstract: | Nedavno sta Polat in Sabidussi v [On the geodesic pre-hull number of a graph, Europ. J. Combin. 30 (2009), 1205--1220] vpeljala invarianto ko-točkovno pred-ovojnično število ▫$mathrm{ph}(G)$▫ grafa ▫$G$▫, ki meri nekonveksnost konveksnega prostora. Vpeljemo podobno invarianto imenovano konveksno pred-ovojnično število, ki je naravna zgornja meja za ko-točkovno pred-ovojnično število. Obe invarianti študiramo na leksikografskem produktu in podamo natančne vrednosti za obe invarianti glede na lastnosti faktorjev. |
