After recapitulating the rudiments of the Kurosh-Amitsur radical theory of S-acts, hereditary radicals are discussed. The hereditary Hoehnke radical assignments r which designate a Rees congruence r(A) to each S-act A, are the hereditary Kurosh-Amits

A *-primitive involution ring Ris either a left and right primitive ring or a certain subdirect sum of a left primitive and a right primitive ring with involution exchanging the components. An example is given of a left and right primitive ring which

A radical γ has the Amitsur property, if γ(A[x]) = (γ(A[x]) ∩ A)[x] for every ring A. To any radical γ with Amitsur property we construct the smallest radical γ x which coincides with γ on polynomial rings. Distinct special radicals with Amit

For any partition of simple prime rings the lower special radical L determined by is properly contained in the upper radical U of all subdirectly irreducible rings with heart in . Under certain constraints on the class it can be achieved that a polyn

We prove that polynomial rings in one indeterminate over nil rings are antiregular radical and uniformly strongly prime radical. These give some approximations of Köthe's problem. We also study the uniformly strongly prime and superprime radicals of

If ϱ is a radical of near-rings and ϱ is its supplementing radical, then ϱ(N)⊕ϱ(N) ⊲ N. We address the issue when ϱ(N) ⊕ϱ(N) = N holds. In the variety F of near-rings in which the constants form an ideal, the assignment c: N → Nc is a h
