Институт по математика и информатика - БАН Block 8, 1113 БАН IV км., СофияСледващото заседание на семинара ще се проведе на 1 юни 2018 г. (петък) от 13:00 часа в зала 578 на ИМИ – БАН. Доклад на тема ON THE NILPOTENCY INDEX OF NIL ALGEBRAS ще изнесе Matyas DOMOKOS (Renyi Institute, Budapest). Резюме. Kaplansky proved in 1946 that finitely generated associative nil algebras (over an infinite base field) of bounded nil index are nilpotent. For positive integers n and m (and a fixed infinite base field) denote by d(n,m) the minimal positive integer d such that any nil algebra R generated by m elements and having bounded nil index n is nilpotent of nilpotency degree d. Recent results of Derksen and Makam on generators of rings of matrix invariants together with a theorem of Zubkov from 1996 [...]
