Square Roots and the Polar Decomposition, eigenvalues of . on its diagonal. Among other things, this allows us to define . of a normal matrix . in a natural way. Let . be any functions on ℂ. If Λ = diag (λ.,…, λ.) is a diagonal matrix with λ. as its diagonal entries, define .(Λ) to be the diagonal matrix diag (.(λ.),…,.(λ.)), and if . = .Λ.*, put .(.) = .(Λ).*.

Hilbert Spaces,bstract in the definition of a norm. What is missing in the theory so far is an appropriate concept of angle and the associated notion of .. These ideas depend on the introduction of an . Hilbert spaces are special kinds of Banach spaces whose norms arise from inner products.

The Resolvent and The Spectrum,lues of .. In infinite dimensions there are complications that arise from the fact that an operator could fail to be invertible in different ways. Finding the spectrum is not an easy problem even in the finite-dimensional case; it is much more difficult in infinite dimensions.
