CASA Function: imult
Intersection-multiplicity of two plane curves in affine space.
Calling Sequence:
Parameters:
- A : planecurve
- algebraic set in implicit representation specifying a planecurve
- B : planecurve
- algebraic set in implicit representation specifying a planecurve
- point : list
- a point given as a list with two entries.
Result:
- m : integer
- the intersection multiplicity of he given curves in the given point
Description:
- The funtion computes the intersection-multiplicity at point of the two plane curves.
Examples:
> a1:=mkImplAlgSet([x^4-y^2],[x,y]);
> a2:=mkImplAlgSet([expand(x^4-y^3)],[x,y]);
> imult(a1,a2,[0,0]);
