Examples
An orthonormal sequence in a Hilbert space is a simple example of a weakly convergent sequence, with limit equal to the 0 vector.
Complete orthonormal systems of wave functions appear naturally as the eigenfunctions of the Hamiltonian (of a bound system ) in quantum mechanics that measures the energy levels, which are called the eigenvalues.
For simplicity, we assume that they are discrete, and that they are orthonormal, i.e., : Note that these basis states are assumed to be independent of time.
Any complete inner product space V has an orthonormal basis.
An orthonormal basis is a basis where all basis vectors have length 1 and are orthogonal to each other.
In most cases of practical interest, the orthonormal basis comes from an integral or differential operator, in which case the series converges in the distribution sense.
