Remarks on
Fuzzy
Minimal
Groups
In this
paper, we
introduce
and
investigate
some
properties
of fuzzy
minimal
groups. It
is shown
that, the
right and
the left
translations
are
relatively
fuzzy
minimal
continuous.
Moreover, we
prove that
the inverse
image of a
fuzzy
minimal
group under
a fuzzy
minimal
homeomorphism
is also a
fuzzy
minimal
group.

New Results on Behaviors of Functional Voltera IntegroDifferential Equations with Multiple TimeLags
The
paper
deals
with
a
nonlinear
Volterra
integrodifferential
equation
(NVIDE)
with
multiple
timelags.
Conditions
are
obtained
which
are
sufficient
for
stability
(S),
boundedness
(B),
globally
asymptotically
stability
(GAS)
of
solutions,
and
for
every
solution
x of
the
given
(NVIDE)
to
be
belong
to
the
solutions
classes,
such
as L^{1}[0,1)
and
L^{2}[0,1).
We
prove
some
results
on
stability,
boundedness,
global
asymptotic
stability,
integrability
and
square
integrability
properties
of
solutions
of
the
considered
(NVIDE).
The
technique
of
the
proofs
involves
to
construct
some
suitable
Lyapunov
functionals
(LFs).
The
given
conditions
involve
nonlinear
generalizations
and
extensions
of
those
conditions
found
in
the
literature.
The
obtained
results
are
new
and
complement
that
found
in
the
literature.

Fixed Points in an Intuitionistic Menger Space
In this paper, we established common xed point theorems for two pairs of self maps by using the new concept of weakly subsequential continuity (wsc) with compatibility of type (E) in an Intuitionistic Menger space (briefly IM space). We deduce important results in this line by restricting the number of mappings involved.

3Difference Cordiality of Some Special Graphs
Let G be a (p,q) graph. Let f : V (G)→{1,2,...,k} be a map where k is an integer 2<k<p. For each edge uv, assign the label f(u)  f(v). f is called kdifference cordial labeling of G if vf (i)  vf (j)<1 and ef (0)  ef (1)<1 where vf (x) denotes the number of vertices labelled with x, ef (1) and ef (0) respectively denote the number of edges labelled with 1 and not labelled with 1. A graph with a kdifference cordial labeling is called a kdifference cordial graph. In this paper we investigate 3difference cordial labeling behavior of ladder, book, dumbbell graph, and umbrella graph.

Some Results on ΛBanach Frames for Operator Spaces
In this paper, a new notion of ΛBanach frame is introduced as a generalization of retro Banach frame for the space of bounded linear operators.
Some results regarding characterizations and construction of ΛBanach frames are presented. We extend results for retro Banach frame to the class of ΛBanach frame. In the sequel, finite sum of ΛBanach frames for operator spaces has been discussed. Finally, some perturbation and stability results on ΛBanach frames have been given.
