Hebrew University 
Amitsur Algebra Seminar
Time: Thursday, June 2, at 12:00.
Place: room 209, Mathematics building
Speaker: Louis Rowen (BIU)
Title: Embeddings and Tensor Products of Division Algebras (Joint work
with D. Saltman)
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!
