报告摘要：We consider two multi-dimensional generalisations of the dispersionless Kadomtsev-Petviashvili (dKP) equation. For one of these generalisations, we study solutions which are constant on a central quadric. The quadric ansatz leads to a second order ODE which is equivalent to Painleve I or II for the dKP equation, but fails to pass the Painleve test in higher dimensions. The second generalisation of the dKP equation leads to a class of Einstein-Weyl structures in an arbitrary dimension, which is characterised by the existence of a parallel weighted vector field, together with further holonomy reduction. We obtain an explicit local form for a family of Einstein-Weyl spaces belonging to this class, and depending on one arbitrary function of one variable.
