Talk:Dilation (operator theory)

Page contents not supported in other languages.
From Wikipedia, the free encyclopedia

I have rewritten the article. The previous version was one sentence long and not quite correct. Dilation in operator theory is not dilation on metric spaces. Unitary dilations are not the same as isometric ones. I also remove the mathematical analysis part from the stub tag, as it's more of an operator theoretic topic.

Also, T(I - T*T) = (I - TT*)T implies

How would you prove that?

By functional calculus. Approximate the square root function using polynomials. Mct mht (talk) 05:54, 25 April 2010 (UTC)[reply]
