isMultiHomogeneous I
isMultiHomogeneous f
Tests if the input Ideal or RingElement is Homogeneous with respect to the grading on the ring. Homogeneous input is required for all methods to compute characteristic classes.
This method works for ideals in the graded coordinate rings of toric varieties, and hence for products of projective spaces. These can be created directly, or using methods the MultiProjCoordRing method of this package, or with methods from the NormalToricVarieties Package.





Note that for an ideal to be multihomogeneous the degree vector of all monomials in a given generator must be the same.
The object isMultiHomogeneous is a method function.
