On meromorphic solutions of certain type of difference equations
We mainly discuss the existence of meromorphic (entire) solutions of certain type of non-linear difference equation of the form: $f(z)^m+P(z)f(z+c)^n=Q(z)$, which is a supplement of previous results in [K. Liu, L. Z. Yang and X. L. Liu, Existence of entire solutions of nonlinear difference equations, Czechoslovak Math. J. 61 (2011), no. 2, 565--576, and X. G. Qi...
متن کاملExistence of Positive Solutions for Certain Partial Difference Equations
where Pm,n > 0 onN 0 , k, l ∈N0,Ni = {i, i+1, . . .} and i is an arbitrary integer. Throughout this paper, we assume that a, b, c, d are positive constants. A double sequence {Am,n} is said to be a solution of (1.1) if it satisfies (1.1) form≥m0, n≥ n0. A solution {Ai, j} of (1.1) is said to be eventually positive if Ai, j > 0 for all large i and j, and eventually negative if Ai, j < 0 for all ...
متن کاملOscillation Criteria for Certain Third Order Nonlinear Difference Equations
Some new criteria for the oscillation of all solutions of third order nonlinear difference equations of the form ∆ a(n)(∆ 2 x(n)) α + q(n)f (x[g(n)]) = 0 and ∆ a(n)(∆ 2 x(n)) α = q(n)f (x[g(n)]) + p(n)h(x[σ(n)]) with ∞ a −1/α (n) < ∞ are established.
متن کاملNonstandard finite difference schemes for differential equations
In this paper, the reorganization of the denominator of the discrete derivative and nonlocal approximation of nonlinear terms are used in the design of nonstandard finite difference schemes (NSFDs). Numerical examples confirming then efficiency of schemes, for some differential equations are provided. In order to illustrate the accuracy of the new NSFDs, the numerical results are compared with ...
