Özet

Let R be a commutative Noetherian ring with identity. I. Swanson proved in([10]) that every ideal in every commutative Noetherian ring has linear growth of primary decompositions. Later, in([8]), R.Y. Sharp generalized this result to finitely generated modules over R. In the first section we present another (may be simpler) proof of this generalized result. Sharp also proved in([7]) that every proper ideal in R has linear growth of primary decompositions for integral closures of ideals. We extend, in the last section, this result to finitely generated modules over R.
