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) 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! <http://math.huji.ac.il/amitsur.html> --------------------------------------------------------- Technion Math Net-2 (TECHMATH2) Editor: Michael Cwikel <techm@math.technion.ac.il> Announcement from: Gili Schul <gili.schul@mail.huji.ac.il>
