Subgroups of
a Group
In this
paper,
Qfuzzy
subgroups
and normal
Qfuzzy
subgroups of
group G with
respect to
tnorm T are
defined and
investigated
some of
their
properties
and
structured
characteristics.
Next the
properties
of them
under
homomorphisms
and antihomomorphisms
are
discussed.

Economic Order Quantity Models for Price Dependent Demand and Different Holding Cost Functions
Demand
for
any
type
of
item
depends
on
its
nature
like;
sensitivity
for
the
price
and
degree
of
freshness.
Previous
inventory
models
usually
assumed
that
the
demand
of
the
commodities
was
constant
or
stockdependent.
This
paper
develops
an
EOQ
models
for
items
whose
demand
is a
decreasing
function
of
selling
price.
The
first
model
assumes
holding
cost
is
nonlinear
multiplicative
function
of
selling
price
and
time.
In
the
second
model
holding
cost
is
considered

Irreducible & Strongly Irreducible BiIdeals of ΓSoRings
The set of all partial functions over a set under a natural addition
(disjointdomain sum), functional composition and functional relation on them, forms a Γsoring. In this paper we introduce the notions of irreducible biideal, strongly irreducible biideal and strongly prime biideals of Γsorings and we prove that a biideal is strongly irreducible if and only if it is strongly prime in a class of Γsorings.

The AdjacencyJacobsthal Sequence in Finite Groups
The adjacencyJacobsthal sequence and the adjacencyJacobsthal matrix were defined by Deveci and Artun (see [5]). In this work, we consider the cyclic groups which are generated by the multiplicative orders of the adjacencyJacobsthal matrix when read modulo α(α > 1). Also, we study the adjacencyJacobsthal sequence modulo α and then we obtain the relationship among the periods of the adjacencyJacobsthal sequence ...................

On the Third Hankel Determinant for a Subclass of ClosetoConvex Functions
Let A denote the class of all normalized analytic function f in the
unit disc U of the form f(z) = z + Σ^{1}_{n}_{=2} a_{n}z^{n}. The object of this paper is to obtain a bound to the third Hankel determinant denoted by H_{3}(1) for a subclass of closetoconvex functions.

Odd Vertex Equitable Even Labeling of Ladder Graphs
Let G be a graph with p vertices and q edges and A={1,3, . . . ,q} if q is odd or A={1,3, . . . ,q+1} if q is even. A graph G is said to admit an odd vertex equitable even labeling if there exists a vertex labeling f : V (G) → A that induces an edge labeling f٭ defined by f٭ (uv) = f(u)+f(v) for all edges uv such that for all a and b in A, v_{f} (a) v_{f} (b)≤1 and the induced edge labels are 2; 4; : : : ; 2q where v_{f }(a) be the number of vertices v .......................

Solving the
Optimal
Control
Problems
with
Constraint
of Integral
Equations
Via Müntz
Polynomials
In this
study, an
efficient
numerical
scheme is
presented
for solving
a class of
optimal
control
problems
governed by
the form of
the
VolterraFredholm
integral
equation.
The
technique
based upon
approximating
the state
and control
functions by
Müntz
polynomials.
The
numerical
integration
and new
approach
utilized to
discretize
the optimal
control
problem to a
nonlinear
programming
using the
Chebyshev
nodes
together
with the
Gauss
quadrature
rule.
Finally,
numerical
examples
illustrate
the
efficiency
of the
proposed
method.
