Resumen de Linking Number of Singular Links and the Seifert Matrix

James J. Hebda , Chun-Chung Hsieh, Chichen M. Tsau

• We extend the notion of linking number of an ordinary link of two components to that of a singular link with transverse intersections in which case the linking number is a half-integer. We then apply it to simplify the construction of the Seifert matrix, and therefore the Alexander polynomial, in a natural way.
