I have tried to construct the WeylCharacterRing with base_ring
polynomials in q with integer coefficients. There were no complaints
but it seemed to take q to be one of the monomials.
# Defines the ring of polynomials in q with integer coefficients
R.<q> = ZZ[]
# Defines the character ring
KG2 = WeylCharacterRing("G2", base_ring = R, style="coroots")
KG2(q)
I don't know if this is a bug or an error on my part.
Later I will want to take the base_ring to be a ring of symmetric
functions.
How do I do this? Thanks
