Description
|
|
•
|
The command RationalMapImage(F, RM, R, S) returns a constructible set cs which is the image of the variety under the rational map RM.
|
•
|
The command RationalMapImage(CS, RM, R, S) returns the image of the constructible set CS under the rational map RM.
|
•
|
Both rings R and S should be over the same ground field.
|
•
|
The variable sets of R and S should be disjoint.
|
•
|
The number of polynomials in RM is equal to the number of variables of ring S.
