Abstract

In this paper we characterize the radical of an arbitrary‎ ‎submodule $N$ of a finitely generated free module $F$ over a‎ ‎commutatitve ring $R$ with identity‎. ‎Also we study submodules of‎ ‎$F$ which satisfy the radical formula‎. ‎Finally we derive‎ ‎necessary and sufficient conditions for $R$ to be a‎ ‎Pr$\ddot{\mbox{u}}$fer domain‎, ‎in terms of the radical of a‎ ‎cyclic submodule in $R\bigoplus R$‎.‎
