%0 Journal Article %T Relative Knot Invariants: Properties and Applications %A Georgi D. Gospodinov %J Mathematics %D 2009 %I arXiv %X We state Bennequin inequalities in the relative case, and show that the relative invariants are additive under relative connected sums. We show they exhibit similar limitations as their classical analogues. We study relatively Legendrian simple knots and give some classification results. %U http://arxiv.org/abs/0909.4326v1
