    A model in which the base-matrix tree cannot have cofinal branches.Peter Lars Dordal - 1987 - Journal of Symbolic Logic 52 (3):651-664.
    A model of ZFC is constructed in which the distributivity cardinal h is 2 ℵ 0 = ℵ 2 , and in which there are no ω 2 -towers in [ω] ω . As an immediate corollary, it follows that any base-matrix tree in this model has no cofinal branches. The model is constructed via a form of iterated Mathias forcing, in which a mixture of finite and countable supports is used.
