Abstract
In this paper we investigates the existence of positive solutions to the singular discrete boundary value problem{Δ2x(i-1)+q1(i) f1(i
x(i)
y(i))=0
i∈{1
2
...
T}
Δ2y(i-1)+q2(i) f2(i
x(i)
y(i))=0
x(0)=x(T+1)=y(0)=y(T+1)=0
by using cone fixed point theorem
where nonlinear term fk(i
x
y) is singular at (x
y)=(0
0)
