Rational Seifert Surfaces in Seifert Filtered Spaces
No full textRationally null-homologous links in Seifert fibered spaces may be represented combinatorially via labeled diagrams. We introduce an additional condition on a labeled link diagram and prove that it is equivalent to the existence of a rational Seifert surface for the link. In the case when this condition is satisfied, we generalize Seifert\u27s algorithm to explicitly construct a rational Seifert surface for any rationally null-homologous link. As an application of the techniques developed in the paper, we derive closed formulae for the rational Thurston-Bennequin and rotation numbers of a rationally null-homologous Legendrian knot in a contact Seifert fibered space. --author-supplied descriptio

An algorithm to calculate generalized Seifert matrices
No full textFriedl S, Kausik C, Qintanilha JP. An algorithm to calculate generalized Seifert matrices. Journal of Knot Theory and Its Ramifications. 2022.We develop an algorithm for computing generalized Seifert matrices for colored links given as closures of colored braids. The algorithm has been implemented by the second author as a computer program called Clasper. Clasper also outputs the Conway potential function, the multivariable Alexander polynomial, the Cimasoni-Florens signatures and the nullities of a link, and displays a visualization of the C-complex used for producing the generalized Seifert matrices
