A New Model for the Secondary Goal in DEA
(University of Maragheh, 20190401)The purpose of the current paper is to propose a new model for the secondary goal in DEA by introducing secondary objective function. The proposed new model minimizes the average of the absolute deviations of data points ...

Some Results on Polynomial Numerical Hulls of Perturbed Matrices
(University of Maragheh, 20190401)In this paper, the behavior of the pseudopolynomial numerical hull of a square complex matrix with respect to structured perturbations and its radius is investigated.

A Subclass of Analytic Functions Associated with Hypergeometric Functions
(University of Maragheh, 20190401)In the present paper, we have established sufficient conditions for Gaussian hypergeometric functions to be in certain subclass of analytic univalent functions in the unit disc $mathcal{U}$. Furthermore, we investigate ...

Inverse Problem for Interior Spectral Data of the Dirac Operator with Discontinuous Conditions
(University of Maragheh, 20190401)In this paper, we study the inverse problem for Dirac differential operators with discontinuity conditions in a compact interval. It is shown that the potential functions can be uniquely determined by the value of the ...

On the Structure of Metriclike Spaces
(University of Maragheh, 20190401)The main purpose of this paper is to introduce several concepts of the metriclike spaces. For instance, we define concepts such as equallike points, cluster points and completely separate points. Furthermore, this paper ...

Some Observations on Dirac MeasurePreserving Transformations and their Results
(University of Maragheh, 20190401)Dirac measure is an important measure in many related branches to mathematics. The current paper characterizes measurepreserving transformations between two Dirac measure spaces or a Dirac measure space and a probability ...

A Class of Hereditarily $ell_p(c_0)$ Banach spaces
(University of Maragheh, 20190401)We extend the class of Banach sequence spaces constructed by Ledari, as presented in ''A class of hereditarily $ell_1$ Banach spaces without Schur property'' and obtain a new class of hereditarily $ell_p(c_0)$ Banach spaces ...

Fuzzy Best Simultaneous Approximation of a Finite Numbers of Functions
(University of Maragheh, 20190401)Fuzzy best simultaneous approximation of a finite number of functions is considered. For this purpose, a fuzzy norm on $Cleft (X, Y right )$ and its fuzzy dual space and also the set of subgradients of a fuzzy norm are ...

FeketeSzegö Problem of Functions Associated with Hyperbolic Domains
(University of Maragheh, 20190401)In the field of Geometric Function Theory, one can not deny the importance of analytic and univalent functions. The characteristics of these functions including their taylor series expansion, their coefficients in these ...

A FullNT Step Infeasible InteriorPoint Algorithm for Mixed Symmetric Cone LCPs
(University of Maragheh, 20190401)An infeasible interiorpoint algorithm for mixed symmetric cone linear complementarity problems is proposed. Using the machinery of Euclidean Jordan algebras and NesterovTodd search direction, the convergence analysis of ...

On the Linear Combinations of Slanted HalfPlane Harmonic Mappings
(University of Maragheh, 20190401)In this paper, the sufficient conditions for the linear combinations of slanted halfplane harmonic mappings to be univalent and convex in the direction of $(gamma) $ are studied. Our result improves some recent works. ...

Certain Inequalities for a General Class of Analytic and Biunivalent Functions
(University of Maragheh, 20190401)In this work, the subclass of the function class S of analytic and biunivalent functions is defined and studied in the open unit disc. Estimates for initial coefficients of Taylor Maclaurin series of biunivalent functions ...

Functors Induced by Cauchy Extension of C$^ast$algebras
(University of Maragheh, 20190401)In this paper, we give three functors $mathfrak{P}$, $[cdot]_K$ and $mathfrak{F}$ on the category of C$^ast$algebras. The functor $mathfrak{P}$ assigns to each C$^ast$algebra $mathcal{A}$ a preC$^ast$algebra ...

On Periodic Shadowing Property
(University of Maragheh, 20190401)In this paper, some properties of the periodic shadowing are presented. It is shown that a homeomorphism has the periodic shadowing property if and only if so does every lift of it to the universal covering space. Also, ...

Common Fixed Point in Cone Metric Space for $mathbf{s}mathbf{varphi}$contractive
(University of Maragheh, 20190401)Huang and Zhang cite{Huang} have introduced the concept of cone metric space where the set of real numbers is replaced by an ordered Banach space. Shojaei cite{shojaei} has obtained points of coincidence and common fixed ...

Admissible Vectors of a Covariant Representation of a Dynamical System
(University of Maragheh, 20190401)In this paper, we introduce admissible vectors of covariant representations of a dynamical system which are extensions of the usual ones, and compare them with each other. Also, we give some sufficient conditions for a ...
