Essential-small fully stable modules

We will add new types of modules over a ring \mathfrak{R} called \mathit{g}- small completely stable module and \mathit{g}- small duo module, assuming \mathfrak{R} is a ring with identity and \mathcal{M} is a unitary left \mathfrak{R}-module. We also present the \mathit{g}- small dual stable module, which is a duality. We show that our new ideas have characterization and a few properties.
