Seifert Form
For 
a given Knot in 
, choose a Seifert Surface 
in for and abicollar 
in 
. If 
is represented by a 1-cycle in 
,let 
denote the homology cycle carried by 
in the bicollar. Similarly, let 
denote 
.The function 
defined by
where lk denotes the Linking Number, is called a Seifert form for
