Query: An incidence Hopf Algebra of Convex Geometries   A lattice L is "meet-distributive" if for each element of L, the meets of the
elements directly below it form a Boolean lattice. These objects are in
bijection with "convex geometries", which are an abstract model of convexity.
Do they give rise to an incidence Hopf algebra of convex geometries?
