“…These properties, not yet proven for all n, can be the object of posterior theoretical studies that are out of the scope of this work. For instance, the CD of an orthogonal MPS where {a 2 n } n≥0 and {b 2 n } n≥0 vanish can be studied analogously to the case where a 1 n = a 2 n = 0, n ≥ 0, which is treated in [9], although with an increase in technical difficulties. Results due to Theorem 3.1 Results fulfilled for n = 0, .…”
