A Decomposition of Pairwise Continuity
In this paper, we introduce and study the notions of some weaker forms of Ti-θ-open sets and some stronger forms of (i, j)-t-sets and (i, j)-B-sets in bitopological spaces. Also, we introduce various forms of pairwise continuity and using these we obtain some decompositions of pairwise continuity.

Common Fixed Point Theorems in Ordered Menger Spaces
The purpose of this paper is to prove common fixed point results for a wide class of contractive mappings in ordered probabilistic metric space. Our results are extensions of the results of Nieto and Rodriguez-Lopez, as well as Ran and Reurings on fixed points of mappings in ordered metric spaces. On the other hand, results of Fang, Mishra, Singh and Jain, as well as Razani and Shirdaryazdi are generalized using partial order and corresponding conditions for the given mappings. Results of several other authors are also partially generalized. |

Newton
and
Steffensen
Type
Methods
with
Flexible
Order
of
Convergence
New
families
of
Newton
and
Steffensen
type
methods
are
derived
by
amalgamating
known
methods.
The
methods
in the
new
families
are of
higher
order
than the
methods
amalgamated.
The
technique
shows
that it
is
possible
to
develop
methods
of any
desired
order. |

Total
Mean
Cordiality
of
Umbrella,
Butterfly
and
Dumbbell
Graphs
A Total
Mean
Cordial
labeling
of a
graph G
= (V,E)
is a
function
f : V
(G)
→{0. 1.
2}
such
that for
each
edge xy
assign
the
label [(f(x)+f(y))/2]
where x,
y
2
V (G)
and
|evf
(i) -evf
(j)|
≤
1, i, j
2
{0. 1.
2}
where evf
(x)
denotes
the
total
number
of
vertices
and
edges
labeled
with x
(x = 0,
1, 2).
If there
exists a
total
mean
cordial
labeling
on a
graph
G,
we will
call
G is
Total
Mean
Cordial.
In this
paper,
we
investigate
the
Total
Mean
Cordial
labeling
behavior
of fan,
umbrella,
dumbbell,
and
buttery
graphs.

On
Sequence
Spaces
Equations
of The
Form Et
+ Fx
=
Fb
for Some
Triangle
T
Given
any
sequence
a=(an)n≥1
of
positive
real
numbers
and any
set E of
complex
sequences,
we write
Ea
for the
set of
all
sequences
y=(yn)n≥1
such
that y/a
= (yn/an)n≥12E; in
particular, s(c)a
denotes
the set
of all
sequences
y such
that y/a
converges. |
