[edit] Unbounded operator

Note: Unbounded operator redirects here but this page provides no information on that topic yet. —Ben FrantzDale 00:20, 15 December 2006 (UTC)

This article gives the wrong suggestion that a closed operator needs to be defined on a linear subspace of some space B with values in the same space B. Actually the domain and range of a closed operator can be contained in different spaces.˜˜˜˜
