We describe all pairs of semigroups S and radicals ρ, such that ρ is invariant in S-graded rings. This generalises several known results due to Amitsur and Sands.

We present an approach to the exponential function, and power functions in general, based on rational power functions and rational approximation of real numbers. For positive a?l we define a function Ea by setting Ea (x) = lim axn for any rational se

We examine in detail some aspects of the algebra of functions (with respect to pointwise addition and multiplication) as encountered in an elementary calculus course. The set of functions whose domains have finite complements furnishes an example of

Motivated by some results and concepts from radical theory for abelian groups, we investigate the radical classes R of associative rings for which there is an infinite cardinal number α such that for every ring A and every a e R(A) we have a e R(B)

Bijective correspondences are established between the radical classes R (in a variety W of rings) with the property that a ring A is in R exactly when its finitely generated subrings are all in R, and certain filters of ideals in a free W-ring. It fo

Let V be a variety of rings and let A ∊ V. The ring A is injective in V if every trianglewith C ∊ V, m a monomorphism and f a homomorphism has a commutative completion as indicated. A ring which is injective in some variety (equivalently, injecti
