Mrežna homologija vozlov : magistrsko delo

Šipec, Katarina (author), Strle, Sašo (mentor)

V tem delu opišemo tri vrste mrežne homologije vozlov - popolnoma blokirano, neblokirano in enostavno blokirano homologijo. Predstavljene so povezave z nekaterimi drugimi vozelnimi invariantami, natančneje s Seifertovimi ploskvami, rodom vozla, Alexandrovim polinomom in razvozlavnim številom.

• Title: Grid homology for knots

Abstract

We describe three types of grid homology for knots - fully blocked, unblocked and simply blocked homology. Connections to some other knot invariants are presented, in particular to Seifert surfaces, the knot genus, the Alexander polynomial and the unknotting number.
