[edit] Another notion of oscillation
There is also another notion -- oscillation of a function (say from a topological space to a metric space) defined by
(It is commonly used that the set of points of discontinuity is a Gδ set.) Do we have this notion defined in some other article on wiki? If not, perhaps an article oscillation of a function could be started. --Kompik 10:47, 7 October 2007 (UTC)
