On the operator equation tht k

Webwhere the hat denotes an operator, we can equally represent the momentum operator in the spatial coordinate basis, when it is described by the differential operator, ˆp = −i!∂x, or in the momentum basis, when it is just a number pˆ= p. Similarly, it would be useful to work with a basis for the wavefunction which is coordinate independent.WebThe distance formula ‖Tt-λI) −1 ‖=[Dist(λ, σ(T)] −1, λ∉σ(T), for hyponormal operators, is generalized top-hyponormal operators for 0
