The following code fails, probably due to a faulty translation between the Oscar and the Singular side:
Oscar
Singular
R, (x,y,z) = QQ["x", "y", "z"] R_ext, _ = PolynomialRing(R, ["u", "v", "w"]) S, (u,v,w) = grade(R_ext, [1,1,1]) f = AlgebraHomomorphism(S, S, [u*v^2, u*w^2, u*v*w]) K = kernel(f)
Interestingly, if one writes [u^2, v^2, w^2] in the map definition, it nevertheless outputs the correct kernel.
[u^2, v^2, w^2]

Yes, I think this is also #975 and #976 :-(
Sorry, something went wrong.
AlgebraHomomorphism is no more, but if I use hom this seems to work now?
