Abstract
Let $R$ be a ring and $M$ be a unital left $R$-module. We define $\mu^{\ast}$-essential extension relation on the set of submodules of $M$ and investigate its properties. Moreover, we define $H$-$\mu^{\ast}$-essential-supplemented on $M$ and investigate the relations between $M$ and direct summand of its submodules.
