  • Convergence of Euler-Maruyama Method for Stochastic Differential Equations
           Driven by alpha-stable Levy Motion

    • Authors: Bahram Tarami, Mohsen Avaji
      Abstract: In the literature, the Euler-Maruyama (EM) method for approximation purposes of stochastic differential Equations (SDE) driven by alph-stable Levy motions is reported. Convergence in probability of this method was proven but it is surrounded by some ambiguities. To accomplish the method without ambiguities, this article has derived convergence in probability of numerical EM method based on diffusion given by semimartingales for SDEs driven by alpha-stable processes. Some examples are provided, their numerical solution are obtained and theoretical results are reconfirmed. The  adopted method could be applied to other subclasses of semimartingales.

  • The Odd Log-Logistic Poisson-G Family of Distributions

    • Authors: Morad Alizadeh, Haitham M. Yousof, Mahdi Rasekhi, Emrah Altun
      Abstract: We propose a new class of continuous distributions with two extra shape parameters named the Odd Log-Logistic Poisson-G family. Some of its mathematical properties including moments, quantile and generating functions and order statistics are obtained. We estimate the model parameters by the maximum likelihood method and present a Monte Carlo simulation study. The importance of the proposed family is demonstrated by means of three real data applications. Empirical results indicate that proposed family provides better fits than other well-known classes of distributions in real applications.

  • On the q-parametric Stancu type Dunkl generalization of the
           Kantorovich-Szasz-Mirakjan operators

    • Authors: Mohammad Mursaleen, Taqseer Khan, Md Nasiruzzaman
      Abstract: In this paper we construct the Stancu type q-Kantrovich-Szasz-Mirakjan operators generated by Dunkl generalization of the exponential function. We obtain some approximation results using the Korovkin approximation theorem for these operators. We also study convergence properties by using the modulus of continuity and the rate of convergence for functions belonging to the Lipschitz class. Furthermore, we obtain the rate of convergence in terms of the classical, the second order, and the weighted modulus of continuity.

  • Observational Modeling of Logical Entropy of Dynamical Systems with local
           approach

    • Authors: Sima Sargazi, Abolfazl Ebrahimzadeh, Zahra Eslami Giski
      Abstract: In this paper, we introduce a new kind of the logical entropy through a local relative approach. The notions of local relative logical entropy and local relative conditional logical entropy from an observer's viewpoint on local relative probability measure space are introduced and some of their ergodic properties are studied. Some properties of the local relative logical entropy of independent partitions are investigated and the concavity property for the local relative logical entropy has been proved. We show that, the basic properties of Shannon entropy of partitions on probability measure spaces, are established for the case of the local relative logical entropy. So the suggested measures can be used besides of the Shannon entropy of partitions. Using the concept of the local relative logical entropy of partitions, we define the local relative logical entropy of a dynamical system and present some of its properties. Finally, it is shown that the local relative logical entropy of dynamical systems is invariant under isomorphism.

  • Weak amenability of semigroup algebras modulo an ideal

    • Authors: Ahmad Mehrabi, Hamidreza Rahimi
      Abstract: The main purpose of this paper is to investigate weak amenability of semigroup algebras. We relate this to a new notion of weak amenability modulo an ideal of Banach algebras. As an important result, we show that $l^1(S)$ is weakly amenable modulo $I_{\sigma}$, where $I_{\sigma}$ is the corresponding ideal of the group congruence $\sigma$.

  • A new modified trust region algorithm for solving unconstrained
           optimization problems

    • Authors: Mohammad Heydari, Tayebeh Dehghan Niri, Seyed Mohammad Mehdi Hosseini
      Abstract: Iterative methods for optimization can be classified into two categories:
      line search methods and trust region methods.
      In this paper, we propose a modified regularized Newton method without line search for minimizing nonconvex
      functions whose Hessian matrix may be singular.
      The proposed method is proved to converge globally if the Gradient and Hessian of the objective
      function are Lipschitz continuous.
      Moreover, we report numerical results that show that the proposed algorithm is competitive with the existing methods.

  • Numerical range of simple graphs and some bounds for their eigenvalues

    • Authors: Maliheh Tajarrod, Tahereh Sistani
      Abstract: The numerical range of a simple graph G, named F(G), is the numerical
      range of its adjacency matrix A(G). The main purpose of this paper was
      to approximate F(G). Then, using this approximation, bounds for the largest

           equations

    • Authors: Ghasem Soleimani Rad, Kamal Fallahi, Zoran Kadelburg
      Abstract: In this paper, we define a generalized $c$-distance in $tvs$-cone$b$-metric spaces and introduce some results about its properties.Then we prove some new fixed point and common fixed point results(with the underlying cone which is not normal). Respective resultsconcerning mappings without periodic points are also deduced. Someexamples are presented to validate our obtained results. Anapplication to system of Fredholm integral equations is presented.

  • Image Zooming Using Barycentric Rational Interpolation

    • Authors: Ghasem Barid Loghmani, Ali Mohammad Esmaili Zaini, Ali Mohammad Latif
      Abstract:  Image zooming is one of the important issues of image processing that maintains the quality and structure of image. Zooming an image necessitates placing the extra pixels in the image data. Moreover, adding the data to the image must be consistent with the texture in the image in order to prevent artificial blocks. In this study, the required pixels are estimated using barycentric rational interpolation. The proposed method is a non-linear one which can preserve the edges and reduces the blur and block artifacts on the zoomed image. Numerical results are presented using PSNR and SSIM fidelity measures and they are compared to some other methods. The average PSNR of the original image and image zooming was 33.08 which can prove that image zooming is very similar to the original image. The experimental results revealed that the proposed method had a better performance compared to other methods and could provide good image quality.

  • The arithmetical rank of k-complete ideals

    • Authors: Luis A. Dupont, Daniel Mendoza, Miriam Rodríguez
      Abstract: We introduce the notions of algebraic and arithmetic derivation. As an application, we use the combinatorial decomposition of an ideal to provide a constructive method to find the algebraic invariants, as the arithmetical rank,  for a family of squarefree monomial ideals, the $k$--complete ideals $I_k^n,$ also known as squarefree Veronese ideals of degree $k$.

  • Weak Shadowing as a Generic Property for IFS's

    • Authors: Mehdi Fatehi Nia
      Abstract: In this paper we consider shadowing and weak shadowing properties for iterated function systems IFS and give some results on these concepts. At first, a sufficient condition for shadowing property is given and by this result we present two IFS which have the shadowing property. It is proved that every uniformly expanding as well as every uniformly contracting  IFS has the weak shadowing property.  By an example we show that in  IFS's   shadowing property does not implies  weak shadowing property. Finally  we have the main result of the paper and prove  that the weak shadowing  is a generic property in the set of all IFS's.

    • Authors: Reza Ezzati, K Maleknejad, Reza Jafari
      Abstract: In this paper, rst, a numerical method is presented for solving generalized linear andnonlinear Lane-Emden type equations. The operational matrix of derivative is obtainedby introducing hybrid third kind Chebyshev polynomials and Block-pulse functions. Thismatrix with the tau method is then utilized to transform the dierential equation into asystem of algebraic equations. Finally, the convergence analysis is investigated and theeciency of the proposed method is indicated by some numerical examples.

  • Using the Outer Approximation Algorithm For Generating All Efficient
           Extreme Points of DEA

    • Authors: Javad Gerami
      Abstract: In this paper, we propose a multiple objective linear programing (MOLP) problem, whose feasible region is same of the production possibility set of the data envelopment analysis (DEA) with variable return to scale (VRS).We show that efficient points of the MOLP in outcome space are corresponding to efficient units of DEA and vice versa. We use the outer approximation algorithm for generating all extreme efficient points in the outcome set of the MOLP problem, then, we obtain the extreme efficient units of the VRS DEA. Because it works in the outcome set rather than in the decision set of the MOLP problem, the outer approximation algorithm has several advantages over decision set-based algorithms. It is also relatively easy to implement. We also consider some extensions.

  • J-Armendariz rings

    • Authors: Maboubeh Sanaei, Shervin Sahebi, Hamid H. S. Javadi
      Abstract: We introduce the notion of J-Armendariz rings, which are
      a generalization of weak Armendariz rings and investigate their proper-
      ties. We show that local rings are J-Armendariz. Also, we prove that a
      ring R is J-Armendariz if and only if R[[x]] is J-Armendariz. It is shown
      that the J-Armendariz property is not Morita invariant. As a specic
      case, we show that the class of J-Armendariz rings lies properly between
      the class of one-sided quasi-duo rings and the class of perspective rings.

  • A New Perspective via Fractional Calculus for the Radial Schrödinger
           Equation

    • Authors: Okkes Ozturk
      Abstract: Differintegral theorems are applied to solve some ordinary differential equations and fractional differential equations. By using these theorems, we obtain different results in the fractional differintegral forms. In this paper, we aim to solve the radial Schrödinger equation under the potential $ V(r)=H/r^{2}-K/r+Lr^{\kappa} $ in $ \kappa=0,-1,-2 $ cases. We also obtain the solutions in the hypergeometric form.
