gfanHomogeneitySpace -- homogeneity space of a list of polynomials



This method computes the homogeneity space of L or M or I. If a MarkedPolynomialList is used, then the marked terms are simply ignored.

i1 : QQ[x,y,z];
i2 : gfanHomogeneitySpace {x+y^2, y+z^2}

o2 = Fan{...1...}

o2 : Fan

gfan Documentation This program computes the homogeneity space of a list of polynomials - as a cone. Thus generators for the homogeneity space are found in the section LINEALITY_SPACE. If you wish the homogeneity space of an ideal you should first compute a set of homogeneous generators and call the program on these. A reduced Groebner basis will always suffice for this purpose.Options:
