Grafovski retrakti : doktorska disertacija

Klavžar, Sandi

Grafovski retrakti so pomemben strukturalni koncept teorije grafov. V drugem poglavju obravnavamo nekatere osnovne rezultate te teorije. Za primer karakteriziramo retrakte enocikličnih grafov, ... vpeljemo pa tudi pojem antiretrakta. V tretjem poglavju obravnavamo retrakte v grafovskih produktih. Dokažemo nekaj dekompozicijskih izrekov za krepki produkt grafov in za leksikografski produkt grafov. Kot stranski rezultat karakteriziramo toge krepke produkte grafov. Za kartezični produkt dokažemo, da so trikotniki prenosljivi za krepko triangulirane grafe, šibko triangulirane grafe in za grafe brez 4-ciklov. V zadnjem poglavju obravnavamo retrakte popolnih grafov. Karakteriziramo retrakte razcepljenih grafov in poiščemo tri enakovredne pogoje za absolutne retrakte razcepljenih grafov. Nadalje dokažemo, da je stopnja povezanosti dedna lastnost retrakcije v razredu grafov intervalov.
