The Kaup–Broer hierarchy can be considered as a certain reduction of the KP hierarchy. Upon introducing the τ‐function the Kaup–Broer system can be formulated in trilinear form giving rise to Wronskian solutions. In this paper several odes of the Painlevé type obtained through reductions of the Kaup–Broer system are considered. Those odes take a trilinear form which allows a linearization.
