ABSTRACT: In this paper, we studied the Friedmann-Robertson-Walker (FRW) space-time with domain walls in the framework of
f(
R,
L
m
,T
)
theory of gravitation. Field equation of
f(
R,
L
m
,T
)
are solved by using two model of
f(
R,
L
m
,T
)
i.e.
f(
R,
L
m
,T
)=R−μ
L
m
T−α
,
f(
R,
L
m
,T
)=R+ζ
L
m
+lT−β
and special form of deceleration parameter with the relation
ρ

=ω
p

. It is observed that the universe is accelerated and expanding.
