Approximative
Reconstruction
Property in
Banach
Spaces
Casazza and
Christensen
in [5]
introduced
and studied
the
reconstruction
property in
Banach
spaces. In
this paper,
we defined
approximative
reconstruction
property
(ARP) in a
Banach space
and give
examples for
the
existence of
ARP. A
necessary
and
sufficient
condition
for a Banach
space to
have an
approximative
reconstruction
property is
given.
Finally, we
give some
PaleyWiener
type
perturbations
results
concerning
the
approximative
reconstruction
property in
Banach
spaces.

The
focus
of
this
paper
is
to
define
some
special
matrices
like
r−circulant,
circulant,
semicirculant,
Hankel
and
Toeplitz
matrices
with
the
help
of
integer
sequences.
In
particular,
this
work
is
focusing
on
obtaining
norms
of
the
afore
mentioned
types
of
matrices
that
are
involved
with
PellPadovanlike
sequences.
Furthermore,
the
upper
and
lower
bounds
of
spectral
norms
of
those
matrices
have
been
also
determined.

A New View on Fuzzy F*Structure Homotopy and its F*Fundamental Group
In this paper, the concept of fuzzy F*structure isomorphisms between F*fundamental groups are studied. Also it is shown that, for every fuzzy F*structure continuous function, there is an induced fuzzy F*structure group ho momorphism between their F*fundamental groups. Further in fuzzy F*path connected space, all the F*fundamental groups π1((X, I), xλ) are fuzzy F*isomorphic.
Also in fuzzy F*path connected space, the F*fundamental group π1((X, I), xλ) is independent of the fuzzy base point xλ up to fuzzy F*structure isomorphism of groups.

Some Special Features of Relative Intuitionistic Dynamical Systems
This study has investigated the properties of the relative intuitionistic
dynamical systems, and a series of essential properties, including (αβ,(µ,ν))−hole, (µ,ν)αβ−minimal, and (µ,ν)αβ−transitive, are introduced and examined. In this paper, it has also been specified in which conditions the relative intuitionistic dynamical system is an invariant system. Finally, an example of the relative intuitionistic dynamical system is presented, and its topologic properties are analyzed.

Generalized
Laguerre
Polynomial
Bounds for
Subclass of
BiUnivalent
Functions
In the
present
paper, we
propose to
introduce a
new subclass
of bi
univalent
analytic
functions
TΣ(λ, γ) (0
< λ ≤ 1, γ ≥
0) which is
defined by
making use
of the
generalized
Laguerre
polynomials
in the open
unit disk ∇.
We derive
upper bounds
for the
coefficients
a2, a3
and discuss
FeketeSzego
problem for
the
functions
belonging to
the new
introduced
class TΣ(λ,
γ).

Existence
and
Uniqueness
Results for
a Class of
Nonlinear
Fractional
Differential
Equations
with
Nonlocal
Boundary
Conditions
In this
paper, we
study the
existence
and
uniqueness
of solutions
for
fractional
differential
equations
with
fractional
integral and
Caputo
fractional
derivatives
in boundary
conditions.
Our analysis
relies on
the Banach
contraction
principle,
Schauder
fixed point
theorem and
Krasnoselskii’s
fixed point
theorem.
Examples are
provided to
illustrate
the main
results.

Exact
Bahadur
Slope for
Combining
Independent
Tests in
Case of
Laplace
Distribution
Combining n
independent
tests of
simple
hypothesis,
vs
onetailed
alternative
as n
approaches
infinity, in
case of
Laplace
distribution
L(γ, 1) is
proposed.
Four
freedistribution
”nonparametric”
combination
procedures
namely;
Fisher,
logistic,
sum of
Pvalues and
inverse
normal were
studied.
Several
comparisons
among the
four
procedures
using the
exact
Bahadur’s
slopes were
obtained.
Results
showed that
the sum of
pvalues
procedure is
better than
all other
procedures
under the
null
hypothesis,
and the
inverse
normal
procedure is
better than
the other
procedures
under the
alternative
hypothesis.

Geometry of
Contact
CRWarped
Product
Submanifolds
on Nearly
Cosymplectic
Manifolds
In this
paper, we
study
contact
CRwarped
products
submanifolds
on nearly
cosymplectic
manifolds.
We work out
the
characterizations
in terms of
tensor
fields under
which a
contact CRsubmanifold
of a nearly
cosymplectic
manifold
reduces to a
warped
product
submanifold.
In the
beginning,
we obtain
some
theorems and
lemmas and
then develop
the general
sharp
inequalities
for squared
norm of the
second
fundamental
form on
nearly
cosymplectic
manifolds.
