QEtaModularEquationQ computes a modular polynomial with coefficients in ZZ
of two functions with coefficients in QQ
.
- modularPolynomial: (AnC, AnC) -> Polynomial Integer
modularPolynomial(x,y)
returns modularPolynomial(x
,y
,[]).
- modularPolynomial: (AnC, AnC, List NonNegativeInteger) -> Polynomial Integer
modularPolynomial(x,y,d)
computes a nonzero polynomial pol such that pol(x
,y
) is zero. It uses (up to) 4 numbers given by the listd
to print intermediate debugging. The valuse are given to oneVerboseStep!.
- modularPolynomial: (List AnC, List Symbol, List NonNegativeInteger, String, String) -> Polynomial Integer
modularPolynomial(gens,syms,d,dir,var)
returns modularPolynomial(gens
,syms
,d
), if var=””. Otherwise, if there is a file given by filename(dir
,var
,”input”), then (before doing any actual compuation) its first line is read, converted to a polynomial and returned. If that file does not exist, then the directory is created, the modular polynomial is computed via poly:=modularPolynomial(gens
,syms
,d
) and its value is written to the file given above. The content of the file will look like “var:=poly;”.
