Almost periodic sequence solutions of a discrete Lotka–Volterra competitive system with feedback control

Nonlinear Analysis: Real World Applications, 2009
The authors study the existence and uniqueness of almost periodic solutions for the following discrete Lotka-Volterra competitive system with feedback control \[ \begin{aligned} x_1(n+1) &= x_1(n)\exp\{r_1(n)(1- x_1(n)K^{-1}_1(n)- \mu_2(n)x_2(n)- b_1(n)u_1(n))\},\\ x_2(n+ 1) &= x_2(n)\exp\{r_2(n)(1- x_2(n)K^{-1}_2(n)- \mu_1(n)x_1(n)- b_2(n) u_2(n))\},\\

On Almost-Periodic Operators in the Spaces of Sequences

Acta Applicandae Mathematica, 2001
The author presents some results concerning the norm and the invertibility of the almost-periodic discrete operators of the form \[ (Ax)(n)=\sum_{m\in Z}A(n,m)x(m)\qquad n\in Z \] acting in spaces of sequences with values in a Banach space \(E\). Among the considered spaces of sequences there are the spaces \[ l^p(E)=\left\{ x=\{ x(n)\} _{n\in Z} \Bigl|
