| Abstract |

|
|
| For a (group)G-graded ring R and any submonoid H of the center Z(G) containing the identity element e of G we define a G-gradation on the semigroup ring R[H] such that R[H]e congruent-to R(H) where R(H) = +h is-an-element-of H R(h) subset-or-equal-to R, and then we give some applications of the new gradations to graded rings and I-adic filtrations. |
