Abstract
We give an explicit formula to compute the rotation number of a nullhomologous Legendrian knot in contact (1/ n)-surgery diagrams along Legendrian links and obtain a corresponding result for the self-linking number of transverse knots. Moreover, we extend the formula by Ding-Geiges-Stipsicz for computing the d -invariant to (1/ n)-surgeries. [ABSTRACT FROM AUTHOR]
