Field Isomorphism and the Normal Closure
Testing whether two number fields are isomorphic, computing the isomorphisms, and constructing the normal closure.
Every page in the KEVOS library tagged splitting field. 2 pages.
Testing whether two number fields are isomorphic, computing the isomorphisms, and constructing the normal closure.
What computing a Galois group means, why the splitting field cannot be constructed, and the transitive group classification that makes the problem finite.
