Global convergence of an inexact interior-point method for convex quadratic symmetric cone programming
(Springer and the Iranian Mathematical Society (IMS), 2016-12-01)In this paper, we propose a feasible interior-point method for convex quadratic programming over symmetric cones. The proposed algorithm relaxes the accuracy requirements in the solution of the Newton equation ...

Growth of meromorphic solutions for complex difference equations of Malmquist type
(Springer and the Iranian Mathematical Society (IMS), 2016-12-01)In this paper, we give some necessary conditions for a complex difference equation of Malmquist type $$sum^n_{j=1}f(z+c_j)=frac{P(f(z))}{Q(f(z))},$$ where $n(in{mathbb{N}})geq{2}$, and $P(f(z))$ and ...

Image processing by alternate dual Gabor frames
(Springer and the Iranian Mathematical Society (IMS), 2016-12-01)We present an application of the dual Gabor frames to image processing. Our algorithm is based on finding some dual Gabor frame generators which reconstructs accurately the elements of the underlying Hilbert space. ...

Multi-valued operators with respect $wt$-distance on metric type spaces
(Springer and the Iranian Mathematical Society (IMS), 2016-12-01)Recently, Hussain et al., discussed the concept of $wt$-distance on a metric type space. In this paper, we prove some fixed point theorems for classes of contractive type multi-valued operators, by using ...

Multiplicity result to some Kirchhoff-type biharmonic equation involving exponential growth conditions
(Springer and the Iranian Mathematical Society (IMS), 2016-12-01)In this paper, we prove a multiplicity result for some biharmonic elliptic equation of Kirchhoff type and involving nonlinearities with critical exponential growth at infinity. Using some variational arguments and ...

On natural homomorphisms of local cohomology modules
(Springer and the Iranian Mathematical Society (IMS), 2016-12-01)Let $M$ be a non-zero finitely generated module over a commutative Noetherian local ring $(R,mathfrak{m})$ with $dim_R(M)=t$. Let $I$ be an ideal of $R$ with $grade(I,M)=c$. In this article we will investigate several ...

On time-dependent neutral stochastic evolution equations with a fractional Brownian motion and infinite delays
(Springer and the Iranian Mathematical Society (IMS), 2016-12-01)In this paper, we consider a class of time-dependent neutral stochastic evolution equations with the infinite delay and a fractional Brownian motion in a Hilbert space. We establish the existence and uniqueness of mild ...

PPF dependent fixed point theorems for multi-valued mappings in Banach spaces
(Springer and the Iranian Mathematical Society (IMS), 2016-12-01)We prove the existence of PPF dependent coincidence points for a pair of single-valued and multi-valued mappings satisfying generalized contractive conditions in Banach spaces. Furthermore, the PPF dependent fixed point ...

Quasilinear Schrödinger equations involving critical exponents in $mathbb{textbf{R}}^2$
(Springer and the Iranian Mathematical Society (IMS), 2016-12-01)We study the existence of soliton solutions for a class of quasilinear elliptic equation in $mathbb{textbf{R}}^2$ with critical exponential growth. This model has been proposed in the self-channeling of a high-power ...

A remark on Remainders of homogeneous spaces in some compactifications
(Springer and the Iranian Mathematical Society (IMS), 2016-12-01)We prove that a remainder $Y$ of a non-locally compact rectifiable space $X$ is locally a $p$-space if and only if either $X$ is a Lindel"{o}f $p$-space or $X$ is $sigma$-compact, which improves two results by ...

A remark on the means of the number of divisors
(Springer and the Iranian Mathematical Society (IMS), 2016-12-01)We obtain the asymptotic expansion of the sequence with general term $frac{A_n}{G_n}$, where $A_n$ and $G_n$ are the arithmetic and geometric means of the numbers $d(1),d(2),dots,d(n)$, with $d(n)$ denoting the number ...

Spacetimes admitting quasi-conformal curvature tensor
(Springer and the Iranian Mathematical Society (IMS), 2016-12-01)The object of the present paper is to study spacetimes admitting quasi-conformal curvature tensor. At first we prove that a quasi-conformally flat spacetime is Einstein and hence it is of constant curvature and the ...
