The trivial topology is the topology with the least possible number of open sets, namely the empty set and the entire space, since the definition of a topology requires these two sets to be open. In particular, it is not a Hausdorff space. Not being Hausdorff, X is not an order topology, nor is it metrizable. pork and rice casserole with mushroom soup
