p-Signature
Diagonalize a form over the rationals to
where all the entries are Integers and
, 
, ...are Relatively Prime to 
. Then the-signature of the form (for 
) is
where
is the number of Antisquares. For 
, the -signature is Sylvester'sSignature.See also Signature (Quadratic Form)- Special Function
