  A. Mahmoodi Kebriya
  20.1001.1.22520201.2013.02.01.1.9

  G. Soleimani Rad

  Recently, Rahimi et al. [Comp. Appl. Math. 2013, In press] defined the conceptof quadrupled fied point in K-metric spaces and proved several quadrupled fixed pointtheorems for solid cones on K-metric spaces. In this paper some quadrupled fixed point resultsfor T-contrac More

  Recently, Rahimi et al. [Comp. Appl. Math. 2013, In press] defined the conceptof quadrupled fied point in K-metric spaces and proved several quadrupled fixed pointtheorems for solid cones on K-metric spaces. In this paper some quadrupled fixed point resultsfor T-contraction on K-metric spaces without normality condition are proved. Obtainedresults extend and generalize well-known comparable results in the literature. Manuscript profile

  3 - G-Frames, g-orthonormal bases and g-Riesz bases
  S. S. Karimizad
  20.1001.1.22520201.2013.02.01.3.1
  G-Frames in Hilbert spaces are a redundant set of operators which yield a representation for each vector in the space. In this paper we investigate the connection betweeng-frames, g-orthonormal bases and g-Riesz bases. We show that a family of bounded operators is a g-B More

  G-Frames in Hilbert spaces are a redundant set of operators which yield a representation for each vector in the space. In this paper we investigate the connection betweeng-frames, g-orthonormal bases and g-Riesz bases. We show that a family of bounded operators is a g-Bessel sequences if and only if the Gram matrix associated to its denes a boundedoperator. Manuscript profile

  4 - Stochastic Non-Parametric Frontier Analysis
  M. Rahmani Gh. Jahanshahloo
  20.1001.1.22520201.2013.02.01.4.2
  In this paper we develop an approach that synthesizes the best features of the two main methods in the estimation of production efficiency. Specifically, our approach first allows for statistical noise, similar to Stochastic frontier analysis, and second, it allows mode More

  In this paper we develop an approach that synthesizes the best features of the two main methods in the estimation of production efficiency. Specifically, our approach first allows for statistical noise, similar to Stochastic frontier analysis, and second, it allows modeling multiple-inputs-multiple-outputs technologies without imposing parametric assumptions on production relationship, similar to what is done in non-parametric methods. The methodology is based on the theory of local maximum likelihood estimation and extends recent works of Kumbhakar et al. We will use local-spherical coordinate system to transform multi-input multi-output data to more exible system which we can use in our approach.We also illustrate the performance of our approach with simulated example.

  5 - Expansion of Bessel and g-Bessel sequences to dual frames and dual g-frames
  M. S. Asgari G. Kavian
  20.1001.1.22520201.2013.02.01.5.3
  In this paper we study the duality of Bessel and g-Bessel sequences in Hilbertspaces. We show that a Bessel sequence is an inner summand of a frame and the sum of anyBessel sequence with Bessel bound less than one with a Parseval frame is a frame. Next wedevelop this re More

  In this paper we study the duality of Bessel and g-Bessel sequences in Hilbertspaces. We show that a Bessel sequence is an inner summand of a frame and the sum of anyBessel sequence with Bessel bound less than one with a Parseval frame is a frame. Next wedevelop this results to the g-frame situation. Manuscript profile

  6 - Computation of the q-th roots of circulant matrices
  M. Amirfakhrian P. Mohammadi Khanghah
  20.1001.1.22520201.2013.02.01.6.4
  In this paper, we investigate the reduced form of circulant matrices and we showthat the problem of computing the q-th roots of a nonsingular circulant matrix A can bereduced to that of computing the q-th roots of two half size matrices B - C and B + C.
