NON-STANDARD FINITE DIFFERENCE METHOD FOR NUMERICAL SOLUTION OF SECOND ORDER LINEAR FREDHOLM INTEGRO-DIFFERENTIAL EQUATIONS
In this article we have considered a non-standard finite difference method for the solution of second order Fredholm integro differential equation type initial value problems. The non-standard finite difference method and the composite trapezoidal quadrature method is used to transform the Fredholm integro-differential equation into a system of equations. We have also developed a numerical met...
متن کاملSTUDYING THE BEHAVIOR OF SOLUTIONS OF A SECOND-ORDER RATIONAL DIFFERENCE EQUATION AND A RATIONAL SYSTEM
In this paper we investigate the behavior of solutions, stable and unstable of the solutions a second-order rational difference equation. Also we will discuss about the behavior of solutions a the rational system, we show these solutions may be stable or unstable.

متن کاملUncountably many bounded positive solutions for a second order nonlinear neutral delay partial difference equation
In this paper we consider the second order nonlinear neutral delay partial difference equation $Delta_nDelta_mbig(x_{m,n}+a_{m,n}x_{m-k,n-l}big)+ fbig(m,n,x_{m-tau,n-sigma}big)=b_{m,n}, mgeq m_{0},, ngeq n_{0}.$Under suitable conditions, by making use of the Banach fixed point theorem, we show the existence of uncountably many bounded positive solutions for the above partial difference equation...
متن کاملAn Algorithm Determining the Difference Galois Group of Second Order Linear Difference Equations
groups are the groups Dk,l,e = {( α 0 0 δ ) ∈ D | α = 1, δ = 1, ααδδ = 1 } with l, k, e ∈ Z≥1 and gcd(k, l, e) = 1, where gα = k gcd(k,l) and gδ = l gcd(k,l) . If G is a one-dimensional algebraic subgroup of D then G is equal to a group Dm,n = {( α 0 0 δ ) ∈ D | αδ = 1 } with m,n ∈ Z. For all m,n ∈ Z we have that Dm,n/D m,n
