1. Lower estimates for a number of closed trajectories of generalized billiards

2. Khovanov Homology and Link Cobordisms
Sammanfattning : Khovanov homology associates to any link in three-dimensional space a bigraded chain complex of Z[c]-modules, whose graded Euler characteristic (after normalization) is the Jones polynomial of the link. The complex is invariant up to homotopy equivalence under ambient isotopy of the link. LÄS MER
3. Projective Links and Their Invariants
Sammanfattning : This thesis consists of two papers about knots and links in the real projective space RP3. We present an algorithm to unknot diagrammatically knots and links in RP3. We extend two classical polynomial invariants of links in R3 to links in RP3. LÄS MER
