Abhyankar's lemma
http://dbpedia.org/resource/Abhyankar's_lemma an entity of type: WikicatLemmas
In mathematics, Abhyankar's lemma (named after Shreeram Shankar Abhyankar) allows one to kill tame ramification by taking an extension of a base field. More precisely, Abhyankar's lemma states that if A, B, C are local fields such that A and B are finite extensions of C, with ramification indices a and b, and B is tamely ramified over C and b divides a, then the compositumAB is an unramified extension of A.
