Integration formulas for the conditional transform involving the first variation
(Springer and the Iranian Mathematical Society (IMS), 2015-06-01)In this paper, we show that the conditional transform with respect to the Gaussian process involving the first variation can be expressed in terms of the conditional transform without the first variation. We then use ...

A certain convolution approach for subclasses of univalent harmonic functions
(Springer and the Iranian Mathematical Society (IMS), 2015-06-01)In the present paper we study convolution properties for subclasses of univalent harmonic functions in the open unit disc and obtain some basic properties such as coefficient characterization and extreme points.

Approximate multi-additive mappings in 2-Banach spaces
(Springer and the Iranian Mathematical Society (IMS), 2015-06-01)A mapping $f:V^n longrightarrow W$, where $V$ is a commutative semigroup, $W$ is a linear space and $n$ is a positive integer, is called multi-additive if it is additive in each variable. In this paper we prove the ...

Notes on amalgamated duplication of a ring along an ideal
(Springer and the Iranian Mathematical Society (IMS), 2015-06-01)In this paper, we study some ring theoretic properties of the amalgamated duplication ring $Rbowtie I$ of a commutative Noetherian ring $R$ along an ideal $I$ of $R$ which was introduced by D'Anna and Fontana. Indeed, ...

On convergence of certain nonlinear Durrmeyer operators at Lebesgue points
(Springer and the Iranian Mathematical Society (IMS), 2015-06-01)The aim of this paper is to study the behaviour of certain sequence of nonlinear Durrmeyer operators $ND_{n}f$ of the form $$(ND_{n}f)(x)=intlimits_{0}^{1}K_{n}left( x,t,fleft( tright) ...

Stochastic functional population dynamics with jumps
(Springer and the Iranian Mathematical Society (IMS), 2015-06-01)In this paper we use a class of stochastic functional Kolmogorov-type model with jumps to describe the evolutions of population dynamics. By constructing a special Lyapunov function, we show that the stochastic functional ...

On meromorphically multivalent functions defined by multiplier transformation
(Springer and the Iranian Mathematical Society (IMS), 2015-06-01)The purpose of this paper is to derive various useful subordination properties and characteristics for certain subclass of multivalent meromorphic functions, which are defined here by the multiplier transformation. Also, ...

On weakly $mathfrak{F}_{s}$-quasinormal subgroups of finite groups
(Springer and the Iranian Mathematical Society (IMS), 2015-06-01)Let $mathfrak{F}$ be a formation and $G$ a finite group. A subgroup $H$ of $G$ is said to be weakly $mathfrak{F}_{s}$-quasinormal in $G$ if $G$ has an $S$-quasinormal subgroup $T$ such that $HT$ is $S$-quasinormal in $G$ ...

Coherence in amalgamated algebra along an ideal
(Springer and the Iranian Mathematical Society (IMS), 2015-06-01)Let $f: Arightarrow B$ be a ring homomorphism and let $J$ be an ideal of $B$. In this paper, we investigate the transfer of the property of coherence to the amalgamation $Abowtie^{f}J$. We provide necessary and ...

A remark on asymptotic enumeration of highest weights in tensor powers of a representation
(Springer and the Iranian Mathematical Society (IMS), 2015-06-01)We consider the semigroup $S$ of highest weights appearing in tensor powers $V^{otimes k}$ of a finite dimensional representation $V$ of a connected reductive group. We describe the cone generated by $S$ as the ...

A posteriori $ L^2(L^2)$-error estimates with the new version of streamline diffusion method for the wave equation
(Springer and the Iranian Mathematical Society (IMS), 2015-06-01)In this article, we study the new streamline diffusion finite element for treating the linear second order hyperbolic initial-boundary value problem. We prove a posteriori $ L^2(L^2)$ and error estimates for this method ...

Some properties of extended multiplier transformations to the classes of meromorphic multivalent functions
(Springer and the Iranian Mathematical Society (IMS), 2015-06-01)In this paper, we introduce new classes $sum_{k,p,n}(alpha ,m,lambda ,l,rho )$ and $mathcal{T}_{k,p,n}(alpha ,m,lambda ,l,rho )$ of p-valent meromorphic functions defined by using the extended multiplier transformation ...

The metric dimension and girth of graphs
(Springer and the Iranian Mathematical Society (IMS), 2015-06-01)A set $Wsubseteq V(G)$ is called a resolving set for $G$, if for each two distinct vertices $u,vin V(G)$ there exists $win W$ such that $d(u,w)neq d(v,w)$, where $d(x,y)$ is the distance between the vertices $x$ and ...

On the bandwidth of Mobius graphs
(Springer and the Iranian Mathematical Society (IMS), 2015-06-01)Bandwidth labelling is a well known research area in graph theory. We provide a new proof that the bandwidth of Mobius ladder is 4, if it is not a $K_{4}$, and investigate the bandwidth of a wider class of Mobius graphs ...
