Abstract:
Noncrossed product division algebras are constructed over all function fields and iterated power series fields over global fields, using Hilbert's Irreducibility Theorem and the construction of [B]. Minimum indexes obtained are p 2 for odd p and 23 otherwise. Examples are obtained with large index to exponent ratio.
