Abstract.In analysis two modes of non-topological convergence are interesting: order convergence and convergence almost everywhere. It is proved here that order convergence of sequences can be induced by a limit structure, even a finest one, whenever it is considered in $\sigma$-distributive lattices. Since convergence almost everywhere can be regarded as order convergence in a certain $\sigma$-distributive lattice, this result can be applied to convergence of sequences almost everywhere and thus generalizing a former result of U. Höhle [11] obtained in a more indirect way by using fuzzy topologies.
