Description |
Example |
Use R ::= QQ[x,y,z]; Points := [[0,0],[1,0],[0,1],[1,1]]; -- a list of points in the plane IntersectionList([ Ideal(x-P[1]z, y-P[2]z) | P In Points]); Ideal(y^2 - yz, x^2 - xz) ------------------------------- Intersection(["a","b","c"],["b","c","d"]); ["b", "c"] ------------------------------- IntersectionList([Ideal(x,y), Ideal(y^2,z)]); Ideal(yz, xz, y^2) ------------------------------- It = Intersection(Ideal(x,y), Ideal(y^2,z)); TRUE ------------------------------- |
