On \(\chi _{mub}\)-lattices and convex substructures of lattices and semilattices. (English) Zbl 0567.06006

The author investigates the following generalization of a lattice: The join of two elements is one of the minimal upper bounds given by a choice function. The meet is defined dually if maximal lower bounds exist and it is equal to the join otherwise. He gives a characterization of such structures arising from convex sublattices of a lattice or semilattice.
