TY - JOUR TT - NIL CLEAN INDEX OF RINGS AU - Basnet, Dhiren Kumar AU - Bhattacharyya, Jayanta PY - 2014 DA - June DO - 10.24330/ieja.266244 JF - International Electronic Journal of Algebra JO - IEJA PB - Abdullah HARMANCI WT - DergiPark SN - 1306-6048 SP - 145 EP - 156 VL - 15 IS - 15 KW - Nil clean ring KW - nil clean index KW - abelian ring N2 - Motivated by the concept of clean index of rings of Lee and Zhou we introduce the concept of nil clean index of rings. For any element a of a ring R with unity, we define η(a) = {e ∈ R | e 2 = e and a−e ∈ nil(R)}, where nil(R) is the set of all nilpotent elements of R. Then nil clean index of R is defined by sup{ |η(a)| : a ∈ R} and it is denoted by Nin(R). In this article, we characterize rings of nil clean indices 1, 2 and 3 and prove some interesting results pertaining them.
