The constraints of unitarity and analyticity on four-body final states are studied. The danger of implementing unitarity, without analyticity, on four-body final states is stressed. We develop a set of relativistic integral equations that incorporate unitarity and analyticity. The subenergy dependence predicted by these equations should find an important application in the phenomenological analysis of four-hadron final states. We work in terms of quasi-two-body states in the isobar model and the equations we obtain are in one vector variable and in principle will be easy to to solve after partial-wave analysis.
