Index -- Optional input for idealizer

Description

This option allows the user to select the starting index for the new variables added in computing Hom(J,J) as a ring. The default value is 0 and is what most users will use. The option is needed for the iteration implemented in integralClosure.

Functions with optional argument named Index :

• idealizer(...,Index=>...) -- Sets the starting index on the new variables used to build the endomorphism ring Hom(J,J)
• "ringFromFractions(...,Index=>...)" -- see ringFromFractions -- find presentation for f.g. ring
