CASA Function: isProjective
Test whether the algebraic set lies in affine or projective space.
Calling Sequence:
Parameters:
- A : algset
-
Result:
- b : boolean
- A boolean value which is true if the given algebraic set lies in projective space.
Description:
- The function tests whether or not the given algebraic set lies in affine (false) or projective (true) space.
Examples:
> a := mkImplAlgSet([x^2-y],[x,y]);
> isProjective(a);
> a := mkImplAlgSet([x^2-y*z],[x,y,z],["basespace"="projective"]);
> isProjective(a);
