WebIn the present chapter we discuss Schmidt’s analogous representation of symmetric integral operators in terms of their eigenvalues and eigenfunctions. Because only square-integrable functions are considered, a function can be treated as a vector with an infinite number of components, and much of the theory traces back to Hilbert’s theory of ...

An interest of the Hilbert-Schmidt operators is that it can be endowed with an inner product, defining S, T H S := ∑ j = 1 + ∞ S e n, T e n . It can be shown with Bessel's equality that this doesn't depend on the choice of the Hilbert basis. how do whales use sound to communicate
