LARGE MAXIMAL SECOND MODULES AND LARGE MAXIMAL SMALL SECOND MODULES
The notions of large maximal second modules and large maximal small second modules are submitted as generalizations of essential second modules and small second modules; respectively, where a T-module V is named a large maximal second module (simply LM second). If for a proper an ideal H of T, then either V H = (0) or V H <LM V and a T-module V is named a large maximal small second module (simply LMS second).Further, if for a proper an ideal H of T, then either V H = (0) or V H <LMS V ,with a number of characteristics and some fundamental features and theorems of these concepts are given. This study also shows the relationship between these ideas and other types of second modules
