For any countable ring R and any non-discrete metrizable ring topology
0, the lattice of all ring topologies admits:
– Continuum of non-discrete metrizable ring topologies stronger than the given topo-
logy 0 and such that sup{ 1, 2} is the discrete topology for any different topologies;
– Continuum of non-discrete metrizable ring topologies stronger than 0 and such that
any two of these topologies are comparable;
– Two to the power of continuum of ring topologies stronger than 0, each of them
being a coatom in the lattice of all ring topologies. |
