cellLabel -- return the label of a cell

Synopsis

Description

The label is provided at the creation of the cell and cannot be modified, neither this function nor any of the cell creation functions attempt to interpret the label and while the labels generally should be monomials, this package makes no attempt to enforce such a requirement.

i1 : R = QQ[x,y];
 
i2 : v1 = newSimplexCell({},x^2);
 
i3 : v2 = newSimplexCell({},x*y^2);
 
i4 : v3 = newSimplexCell {};
 
i5 : e = newSimplexCell {v1,v2};
 
i6 : C = cellComplex(R,{e,v3});
