Hebrew University Amitsur Algebra Seminar ****************************** Time: Thursday, Dec. 1, 12:00-13:15 Place: math 209 Speaker: Gil Alon Title: Homomorphism-like maps on groups Abstract: Let G be a finite group. We will be interested in functions from G to C* whose restriction to any abelian subgroup is a homomorphism. We will prove that nontrivial such functions exist for any nontrivial G, and describe some methods for constructing them on families of simple groups. 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>
