Currently, this does not work:

sage: F0.<x> = FunctionField(GF(3))
sage: R.<y> = F0[]
sage: F.<y> = F0.extension(y^2 - x)
sage: S.<t> = F[]
sage: f = t^2 - x
NotImplementedError

This is implemented here: https://github.com/saraedum/sage/blob/experimental/src/sage/rings/function_field/function_field.py#L1717

Depends on #16564
Depends on #26128

Component: commutative algebra

Keywords: sd59, sd86.5

slelievre, sorry, I don't understand. This is not implemented on any particular branch yet. There is a draft of an implementation at the link above but that branch contains tons of other experimental changes as well.
