摘要

A radical. of rings is said to have the Amitsur property if for all rings A, gamma(A[X]) = (gamma(A[X]) boolean AND A)[ X]. Let X-alpha denote a set of indeterminates of cardinality alpha We say that gamma has the alpha-Amitsur property if for all rings A, gamma(A[X-alpha]) = (gamma(A[X-alpha]) boolean AND A) [X-alpha]. We study properties of this type of radicals and show relationships with other known radicals for rings. A ring A is said to be an absolute gamma-ring if A[x(1,) . . . , x(n)] is an element of gamma, for any n is an element of N. We show that A is an absolute G-ring for the Brown-McCoy radical G, if and only if A is in the radical class S determined by the unitary strongly prime rings. Moreover, A is an absolute nil ring if and only if A is an absolute J-ring, where J denotes the Jacobson radical.
