See also spectral theory for a historical perspective.
It is possible to generalize spectral theory to such algebras.
His research concerns differential equations, scattering theory, and spectral theory.
Such spaces were introduced to study spectral theory in the broad sense.
Some applications have required the development of p-adic functional analysis and spectral theory.
Another proof is based on the spectral theory from which part of the arguments are borrowed.
He established the spectral theory for bounded symmetric operators in a form very much like that now regarded as standard.
Stone was led to it by his study of the spectral theory of operators on a Hilbert space.
He wrote five papers directly related to spectral theory of operators which Hilbert was developing.
There have been three main ways to formulate spectral theory, all of which retain their usefulness.
