Deletion of Tikhonov's theorem

Comment: This is a disambiguation page, although it only contains two extant articles.  Granted, as someone above points out, its purpose could be achieved with a disambig link at the top of both articles.   However, isambiguation says "If there are only two topics to which a given title might refer, and one is the primary topic, then a disambiguation page is not needed – it is sufficient to use a hatnote on the primary topic article, pointing to the other article."   But in this case, it does not appear that one is "primary", so a Disambig page may be appropriate
