Description
In SageMath 9.3.beta1:
sage: R.<x> = QQ[] sage: U.<a> = Qp(2).extension(x^2 + x + 1) sage: F = U.frobenius_endomorphism(); F Frobenius endomorphism on 2-adic Unramified Extension Field in a defined by x^2 + x + 1 lifting a |--> a^2 on the residue field sage: copy(F) Identity endomorphism of 2-adic Unramified Extension Field in a defined by x^2 + x + 1 sage: loads(dumps(F)) Identity endomorphism of 2-adic Unramified Extension Field in a defined by x^2 + x + 1
This is fixed by implementing suitable _extra_slots()
and _update_slots()
methods.
