Assume that
Qis overPthat is overp. We prove that:Ideal.ramificationIdx P Q ≤ Ideal.ramificationIdx p QIdeal.inertiaDeg P Q ≤ Ideal.inertiaDeg p QNote: These results also follow from Ideal.ramificationIdx_algebra_tower and Ideal.inertiaDeg_algebra_tower but they are proved here in a slightly more general situation.
