• Fixed point index
• positive operators
• monotone iterative technique
• elliptic system
• nonzero positive solution

We provide new results on the existence of nonzero positive weak solutions for a class of second-order elliptic systems. Our approach relies on a combined use of iterative techniques and classical fixed point index. Some examples are presented to illustrate the theoretical results.
