**ABSTRACT:**In this paper we establish the asymptotical representations of P(lambda) solutions of k-th order Emden-Fowler difference equation Delta(k) y(n) = alpha p(n)Pi(k-1)(i=0) vertical bar Delta(i) y(n+si)vertical bar(sigma i) sign(y(n+s0)), where p(n) is close to a power sequence. We obtained the necessary conditions for the existence of P(lambda) solutions and we also found the sufficient conditions of their existence for non-critical classes. These results are generalizations of corresponding theorems for second-order Emden-Fowler equation. - [Show abstract] [Hide abstract]

**ABSTRACT:**Infinite Leslie matrices, introduced by Demetrius 40 years ago, are mathematical models of age-structured populations defined by a countable infinite number of age classes. This article is concerned with determining solutions of the discrete dynamical system in finite time. We address this problem by appealing to the concept of kneading matrices and kneading determinants. Our analysis is applicable not only to populations models, but also to models of self-reproducing machines and self-reproducing computer programs. The dynamics of these systems can also be described in terms of infinite Leslie matrices. - [Show abstract] [Hide abstract]

**ABSTRACT:**The boundedness character of positive solutions of the following cyclic system of difference equationswhere A, p and q are positive numbers, and where if, for some and, then denotes, is completely described in this paper. - [Show abstract] [Hide abstract]

**ABSTRACT:**The spectral theory of higher order difference operators is studied by means of asymptotic summation, thereby extending many results of differential operators to the discrete setting. The spectra of degenerate fourth-order operators are also investigated. The results are then compared with those of corresponding differential operators. Even though there are many similarities between both classes of operators, the spectral results may be quite distinct. - [Show abstract] [Hide abstract]

**ABSTRACT:**Exact finite difference schemes and non-standard finite difference schemes are constructed for the first-order differential equation , for and . In particular, we show that the central finite difference scheme is an exact scheme for the differential equation . - [Show abstract] [Hide abstract]

**ABSTRACT:**Let X be a complex Banach space and q >= 2 be a fixed integer number. Let U = {U(n, j)}(n >= j >= 0) subset of L(X) be a q-periodic discrete evolution family generated by the L(X)-valued, q-periodic sequence (A(n)). We prove that the solution of the following discrete problem y(n+1) = A(n)y(n) + e(i mu n)b, n is an element of Z(+), y(0) = 0 is bounded (uniformly with respect to the parameter mu is an element of R) for each vector b is an element of X if and only if the Poincare map U(q,0) is stable. - [Show abstract] [Hide abstract]

**ABSTRACT:**This paper presents a proof of almost sure asymptotic stability of trivial solution of stochastic systems of linear difference equations driven by -integrable martingale-type noise. For this purpose, we exploit a convergence theorem for non-negative semi-martingale decompositions and verify a practical criteria based on non-random eigenvalues. Two 2D examples illustrate the applicability of obtained criteria.
