Definition talk:Isometry (Hilbert Spaces)

I see the "MissingLinks" template and need to ask: to what? --prime mover (talk) 09:24, 11 January 2013 (UTC)

Pertaining to the notation, I have intentionally violated the house style, because such aids comprehension. Effectively, most of functional analysis is generalized linear algebra, and the notation is taken to be similar: $U g$ thus corresponds to $\mathbf {A x}$. Putting excessive parentheses will only hamper understanding. --Lord_Farin (talk) 13:10, 11 January 2013 (UTC)
