Check | elt-alg^boo |  |
### Description The underlying function field. ### Examples x_T := RationalFunctionField(FiniteField(9));;x_TR := PolynomialAlgebra(FiniteField(9));; x_TX := PolynomialAlgebra(x_T);;x_f1:=x_TX.1^2 - x_T.1^3 - x_T.1;;x_f2:=x_TX.1;; x_seq := Sequence([x_f1,x_f2]);; FunctionField(x_seq);
