Oscillation criteria for first-order systems of linear difference equations

open access: yesElectronic Journal of Differential Equations, 2009
In this article, we obtain conditions for the oscillation of vector solutions to the first-order systems of linear difference equations $$displaylines{ x(n+1)=a(n)x+b(n)y cr y(n+1)=c(n)x+d(n)y }$$ and $$displaylines{ x(n+1)=a(n)x+b(n)y+f_1(n) cr
