Computing the adjunction divisor

For any (closed) singular place we determine the multiplicity
, alternatively, by the formula (2)
or the Dedekind formula (cf. Remarks 2.5 and 2.3). Note that to compute a local intersection number (as
appearing in both formulas), we can proceed inductively,
computing the primitive parametrization
of up to degree , until
is less than
