Povzetek: In classical knot theory knots are studied by means of classical knot invariants, such as genus of a knot, Alexander polynomial, Jones polynomial etc.
Research in low dimensional topology has yielded refinements of classical invariants, taking the form of homology theories. A brief introduction to these techniques will be given, focusing on Khovanov homology and knot Floer homology.
