Weakly classical 1-absorbing primary submodules

In this paper, we introduce weakly classical 1-absorbing primary submodules of an unital module over a commutative ring with nonzero identity. Consider [Formula: see text] as a module over a ring [Formula: see text]. A proper submodule [Formula: see text] of [Formula: see text] is called weakly classical 1-absorbing primary submodule, if for each nonunit [Formula: see text] and [Formula: see text] with [Formula: see text], it follows that either [Formula: see text] or [Formula: see text] for some [Formula: see text]. Various properties and characterizations of weakly classical 1-absorbing primary submodules are explored.
