---------------------------+------------------------------------------------
Currently there is no representation of univariate polynomial quotient
rings in the Singular interface; it was only implemented for the
multivariate case.
The attached patch implements it:
{{{
sage: P.<x> = QQ[]
sage: Q.<xi> = P.quo([(x^2+1)])
sage: singular(xi)
xi
sage: singular(Q)
// characteristic : 0
// number of vars : 1
// block 1 : ordering lp
// : names xi
// block 2 : ordering C
// quotient ring from ideal
_[1]=xi^2+1
sage: (singular(xi)*singular(xi)).NF('std(0)')
-1
}}}
