Constant Argument

Consider the first-order delay difference equation with a constant argument Δxn+pnxn-k=0,  n=0,1,2,…, and the delay difference equation with a variable argument Δxn+pnxτn=0,  n=0,1,2,…, where p(n) is a sequence of nonnegative real numbers, k is a positive integer, Δx(n)=x(n+1)-x(n), and τ(n) is a sequence of integers such that τ(n)≤n-1 for all n≥0 and limn→∞τ(n)=∞. A survey on the oscillation of all solutions to these equations is presented. Examples illustrating the results are given.

Delay Difference

We construct a stability cone, which allows us to analyze the stability of the matrix delay difference equation . We assume that and are simultaneously triangularizable matrices. We construct points in which are functions of eigenvalues of matrices ,   such that the equation is asymptotically stable if and only if all the points lie inside the stability cone.
