Introduction A class of random variables called negatively orthant dependent random variables defined in the classical setting of probability spaces by Lehman in 1966. Joag-Dev and Proschan extended this class of random variables and showed every seq

In this paper, we investigate the Hyers-Ulam stability of the orthogonally cubic equation and Pexiderized cubic equation [f(kx+y)+f(kx-y)=g(x+y)+g(x-y)+frac{2}{k}g(kx)-2g(x),]in multi-normed spaces by the direct method and the fixed point method. Mor

A new class of the Ito integral for Brownian motion is defined and studied in the framework of Riesz spaces. The stochastic process with respect to this stochastic integral is non-adapted and it is...

In this paper, we define an orthonormal basis for 2-*-inner product space and obtain some useful results. Moreover, we introduce a 2-norm on a dense subset of a 2-*-inner product space. Finally, we obtain a version of the Selberg, Buzano’s and Bes

Finding a best dual frame that minimizes the reconstruction errors when erasures occur is a deep-rooted problem in frame theory. The primary purpose of this paper is to introduce a new measurement for constructing optimal duals. We consider the numer

In this paper, we introduce the concept of K-fusion frames and propose the duality for such frames. The relation between the local frames of K-fusion frames with their duals is studied. The elements from the range of a bounded linear operator K can b
