rigged Hilbert space
In extensions of Quantum Mechanics [1, 2], the concept of rigged Hilbert spaces allows one “to put together” the discrete spectrum of eigenvalues corresponding to the bound states (eigenvectors) with the continuous spectrum (as , for example, in the case of the ionization of an atom or the photoelectric effect).
Definition 0.1.
A rigged Hilbert space is a pair with a Hilbert space and is a dense subspace with a topological vector space structure for which the inclusion map is continuous. Between and its dual space there is defined the adjoint map of the continuous inclusion map . The duality pairing between and also needs to be compatible with the inner product on :
whenever and .
