multiReesIdeal(...,VariableBaseName=>...) -- choose a base name for variables in the created ring

Usage:

multiReesIdeal(..., VariableBaseName => X)

homIdealPolytope(..., VariableBaseName => X)

Description

Each of these functions creates a new ring of the form $R[X_0,\ldots, X_r]$ or $k[X_0,\ldots, X_r]$, where $R$ is the ring of the input ideal and $k$ is the coefficient ring of the output ideal. This option allows the user to change the base names of the new variables in this ring. The default variable is X.

i1 : S = QQ[x_0..x_3];

i2 : C = trim monomialCurveIdeal(S,{2,3,5});

o2 : Ideal of S

i3 : multiReesIdeal (C, VariableBaseName => "w")

             2                   2
o3 = ideal (x w  - x w  - x w , x w  - x w  - x w )
