RADICALS IN GENERAL Γ-NEAR-RINGS

Abstract

The J ₂ and J ₃ radicals for zerosymmetric Γ-near-rings were recently defined by the author. In the present paper we define the J ₂₍₀₎ and J ₃₍₀₎ radicals for arbitrary Γ-near-rings. These radicals are sirmlar to corresponding ones which were recently defined by Veldsman for near-rings. Let M be a r-near-ring with left operator near-ring L. Then J _κ(0)(L)⁺ = J _{κ (0)} (M), k. = 2,3. If A is an ideal of M, then J _{κ (0)} (A) ⊆ J _{κ (o)}(M) ∩ A, with equality when k = 3 and A is left invariant. J ₃₍₀₎ is a Kurosh-Amitsur radical in the variety of Γ-near-rings.
