This class has static methods that return various polynomials.
static BigPolynomial one(size_t varCount)
Returns the polynomial 1 in the ring VarNames(varCount).
static BigPolynomial one_minus4tt_3ttt_tttt_minusttttt()
Returns the polynomial 1 - 4t^2 + 3t^3 + t^4 - t^5.
static BigPolynomial zero(size_t varCount)
Return the zero polynomial in the ring VarNames(varCount).
static BigPolynomial hilbert_xx_yy_xz_yz()
Returns the multigraded Hilbert-Poincare series numerator of the ideal <x^2, y^2, xz,...
Defines the variables of a polynomial ring and facilities IO involving them.
