on we define an order topology (lexicographic order) as follow: if or ( & ).

Is this topology equivalent to the standard topology? if not, which topology is finer?(give an example of an open set in one but not in the other)?

thanks :)

I wasn't clear enough. if (X,<) is a partial order set, then all (a,b) a<b U (-infinity,infinity) is a base of a topology on X.

now I need to compare this topology with the Euclidean one.

any help or hint is appreciated
