Title: Embeddings and Tensor Products of Division Algebras (Joint work
with D. Saltman)
 
Abstract:
 
Recently L. Small revived two questions from division algebras (finite
dimensional over their centers):
 
Can two division algebras over a common subfield be embedded in a
common division algebra?
 
Is the tensor product over an algebraically closed subfield of the
center of two division algebras necessarily a domain?
 
We have counterexamples to both questions, and will also indicate
where one can find positive results.
 
You are cordially invited!
