Sažetak

All rings are commutative with identity, and all modules are unital. The purpose of this article is to investigate n-absorbing submodules. For this reason we introduce the concept of n-absorbing submodules generalizing n-absorbing ideals of rings. Let M be an R-module. A proper submodule N of M is called an n-absorbing submodule if whenever $a_{1}\cdots a_{n}m\in N$ for $a_{1},\ldots,a_{n}\in R$ and $m\in M$, then either $a_{1}\cdots a_{n}\in (N :_R M)$ or there are $n-1$ of $a_{i}$'s whose product with m is in N. We study the basic properties of n-absorbing submodules and then we study n-absorbing submodules of some classes of modules (e.g. Dedekind modules, Prüfer modules, etc.) over commutative rings.
