Definition talk:Set Derivative

We already have the page Definition:Derived Set which is the set of all limit points of a set.

This may need to be resolved. Different approaches to topology define things in different ways, using different words to define the same thing. Confusion arises if we do not stick to one of these.

Please review the existing definitions and see whether they do mean the same thing (except with different words) or whether there is a subtle difference between what you have defined and what has been defined already in.

Also, please note that the house style requires a rigorous attention to presentational detail. -- prime mover (talk) 17:09, 17 December 2015 (UTC)
