LINEAR DISCRETE CONVOLUTION AND ITS INVERSE. PART 1. CONVOLUTION [PDF]

We present here several ways of calculating the linear discrete convolution, its inverse - the deconvolution, by direct methods, generator functions, Z-transform, using matrices and MATLAB.

Global dynamics of two systems of exponential difference equations by Lyapunov function

, 2014
In this paper, we study the boundedness character and persistence, existence and uniqueness of the positive equilibrium, local and global behavior, and rate of convergence of positive solutions of two systems of exponential difference equations ...

Sharp estimates regarding the remainder of the alternating harmonic series

, 2015
In the present paper we obtain enhanced estimates regarding the remainder of the alternating harmonic series. More precisely, we show that 1 4n2 +a < ∣ ∣∣ ∣ ∣ n ∑ k=1 (−1)k−1 1 k − (−1)n−1 1 2n − ln2 ∣ ∣∣ ∣ ∣ 1 4n2 +b , for all n ∈N , with a = 2 and b ...

On the convergence of double integrals and a generalized version of Fubini's theorem on successive integration

, 2012
Let the function $f: \bar{\R}^2_+ \to \C$ be such that $f\in L^1_{\loc} (\bar{\R}^2_+)$. We investigate the convergence behavior of the double integral $$\int^A_0 \int^B_0 f(u,v) du dv \quad {\rm as} \quad A,B \to \infty,\leqno(*)$$ where $A$ and $B ...

On some generalizations of statistical boundedness

, 2014
Fridy and Orhan (Proc. Am. Math. Soc. 125(12):3625-3631, 1997) introduced the concepts of statistical boundedness, statistical limit superior, statistical limit inferior, and they established an analog of Knopp’s Core Theorem.

On some spaces of almost lacunary convergent sequences derived by Riesz mean and weighted almost lacunary statistical convergence in a real n-normed space

, 2014
In this paper, we introduce some new spaces of almost convergent sequences derived by Riesz mean and the lacunary sequence in a real n-normed space. By combining the definitions of lacunary sequence and Riesz mean, we obtain a new concept of statistical ...

Global stability in n-dimensional discrete Lotka-Volterra predator-prey models

, 2014
There are few theoretical works on global stability of Euler difference schemes for two-dimensional Lotka-Volterra predator-prey models. Furthermore no attempt is made to show that the Euler schemes have positive solutions.

A strong convergence theorem on solving common solutions for generalized equilibrium problems and fixed-point problems in Banach space

Fixed Point Theory and Applications, 2011
In this paper, the common solution problem (P1) of generalized equilibrium problems for a system of inverse-strongly monotone mappings and a system of bifunctions satisfying certain conditions, and the common fixed-point problem (P2) for a family of ...

Generalized spaces of double sequences for Orlicz functions and bounded-regular matrices over n-normed spaces

, 2014
The aim of this paper is to introduce some generalized spaces of double sequences with the help of the Musielak-Orlicz function M=(Mjk) and four-dimensional bounded-regular (shortly, RH-regular) matrices A=(anmjk) over n-normed spaces.
