On ϕ-2-Absorbing Primary Submodules
Let R be a commutative ring with identity and M be a unitary R -module. Let ϕ : S ( M ) → S ( M ) ∪ { ∅ } be a function, where S ( M ) is the set of submodules of M . We say that a proper submodule N of M is a ϕ -2-absorbing primary submodule if r s x ∈ N ∖ ϕ ( N ) implies r x ∈ N , or s x ∈ N , or...

Summary: | Let
R
be a commutative ring with identity and
M
be a unitary
R
-module. Let
ϕ
:
S
(
M
)
→
S
(
M
)
∪
{
∅
}
be a function, where
S
(
M
) is the set of submodules of
M
. We say that a proper submodule
N
of
M
is a
ϕ
-2-absorbing primary submodule if
r
s
x
∈
N
∖
ϕ
(
N
) implies
r
x
∈
N
, or
s
x
∈
N
, or
rs
∈
(
N
:
M
)
, where
r
,
s
∈
R
and
x
∈
M
. In this paper, we study
ϕ
-2-absorbing primary submodules and we prove some basic properties of these submodules. Also, we give a characterization of
ϕ
-2-absorbing primary submodules and we investigate
ϕ
-2-absorbing primary submodules of some well-known modules. |
