Tamely ramified subfields of division algebras
چکیده انگلیسی

For any number field K, it is unknown which finite groups appear as Galois groups of extensions L/K such that L is a maximal subfield of a division algebra with center K (a K-division algebra). For K=Q, the answer is described by the long standing Q-admissibility conjecture.We extend a theorem of Neukirch on embedding problems with local constraints in order to determine for every number field K, what finite solvable groups G appear as Galois groups of tamely ramified maximal subfields of K-division algebras, generalizing Liedahlʼs theorem for metacyclic G and Sonnʼs solution of the Q-admissibility conjecture for solvable groups.
