I believe one can extend the classification to any right-half-plane double complex (with no finiteness restrictions) by allowing for zigzags which extend infinitely down and to the right. Dually one classifies upper-half-plane double complexes. I'm not sure about full-plane double complexes without finiteness restrictions. | |
