A New Type
of Fuzzy
Covering
Property for
Fuzzy
Topological
Spaces
In this
paper, we
introduce
and study a
new type of
fuzzy S-closedness
in a fuzzy
topological
space with
respect to
certain
fuzzy grill
G and
through some
specific
α-shading (0
< α < 1),
named as
fuzzy GSα
-closedness.
The work
done in this
paper
aspires to
get, in a
new
perspective,
certain
analogues of
the results
and
concepts-usually
encountered
in
connection
with the
study of S-closedness
in
topological
and fuzzy
topological
spaces.

Let
R be
a
commutative
ring
with
unity.
The
total
graph
of
R, T
(Γ(R)),
is
the
simple
graph
with
vertex
set
R
and
two
distinct
vertices
x
and
y
are
adjacent
if x
+ y
ϵ
Z(R),
where
Z(R)
is
the
set
of
all
zero
divisors
of
R.
This
paper
presents
a
study
of
some
local
properties
of
the
graph
T (Γ(Zn)).
We
answer
the
question
“
when
is T
(Γ(Zn))
locally
connected?”.
We
also
prove
that
the
neighborhoods
of
any
two
distinct
vertices
in T
(Γ(Zn))
induce
isomorphic
graphs
if
and
only
if n
is
even.

On Conductor Ideals of Quadratic Orders
In this paper we study the orders in quadratic number fields. We give a complete description of conductor ideals of certain orders in quadratic number fields and investigate some of their important arithmetic properties.

On a Measurable Solution of a Class of higher-order Stochastic Heat-type Equation
We give a generalized measurable–predictable solution to a higher–order stochastic parabolic initial–value problem in terms of the further generalized Hermite polynomials. Condition and estimates on the existence and uniqueness of the solution are given. We prove the upper second moment growth bound estimate for the solution and consequently show that the second moment of the solution grows exponentially in time with respect to the parameter λ at the precise rate of 2 + c3λ2Lip2σ , c3 > 0 and ; c3Lip2σ as the noise level increases.

Coefficient
Estimate for
Class of
Meromorphic
Bi-Bazilevic
Type
Functions
Associated
with Linear
Operator
Defined by
Convolution
In the
present
paper, we
propose to
investigate
a new
subclass
Σ⁎,p,qM
(h, µ, λ, k,
γ) of
meromorphic
functions
associated
with linear
operator
defined by
means of
convolution
in the
exterior of
the unit
disk ∇ := {z
ϵ
C : 1 < |z|
< ∞}.
We study the
behaviour of
initial
coefficients
b0,
b1
and b2
for the
function in
this newly
constructed
class. Some
interesting
remarks of
the results
presented
here are
discussed.
Our results
generalize
and improve
some of the
previously
known
results of
other
researchers.

A New
Approach for
Solving
Partial
Differential
Equations
Based on
Finite-Difference
and Haar
Wavelet
Methods
The main
objective of
this paper
is to
develop a
new scheme
based on
finite-difference
and Haar
wavelet for
second order
diffusion
equation and
third order
dispersive
equation.
Further, we
have carried
out the
stability of
the Haar
wavelet. We
solved four
problems
consisting
linear
diffusion
equation and
dispersive
homogeneous
and non
homogeneous
equation to
validate the
developed
scheme.
We have also
compared our
results with
existing
methods such
as finite
difference
method,
global
extrapolation
method and
non
polynomial
spline
method.

Some
3-Divisor
Cordial
Graphs
Derived from
Path
Let G be a
(p, q) graph
and 2 ≤ k ≤
p. Let f : V
(G) → {1, 2,
. . . , k}
be a map.
For each
edge xy,
assign the
label 1 if
either f(x)
or f(y)
divides the
other and 0
otherwise. f
is called a
k-divisor
cordial
labeling if
|vf (i) − vf
(j)| ≤ 1
i, j
ϵ
{1, 2, ...,
k} and |ef
(0) − ef
(1)| ≤ 1
where vf (x)
denotes the
number of
vertices
labeled with
x, where x
ϵ
{1, 2, . . .
, k}, ef (i)
denote the
number of
edges
labeled with
i, i
ϵ
{0, 1}. A
graph with a
k-divisor
cordial
labeling is
called a
k-divisor
cordial
graph. In
this paper,
we obtain
3-divisor
cordial
graphs
derived from
path.

Perturbations
and New
Characterizations
of Woven
P-Frames
In this
paper, we
prove
several
functional-analytic
properties
of weaving
p-frames. We
first prove
that Banach
woven
p-frames are
stable under
small
perturbations.
This is
inspired by
corresponding
classical
perturbation
results for
bases. We
introduce
new and
weaker
conditions
that ensure
the desired
stability.
We then
present
several
approaches
for
identifying
and
constructing
of woven
p-frames. To
this end, we
present some
conditions
under which
a p-frame
and a finite
family of
operators
constitute a
woven
p-frame. |
