    Operator of Time and Generalized Schrödinger Equation by Slobodan Prvanović

    Published 2018-01-01
    “…The equation describing the change of the state of the quantum system with respect to energy is introduced within the framework of the self-adjoint operator of time in nonrelativistic quantum mechanics. In this proposal, the operator of time appears to be the generator of the change of the energy, while the operator of energy that is conjugate to the operator of time generates the time evolution. …”

    An Opial-Type Inequality on Time Scales by Qiao-Luan Li, Wing-Sum Cheung

    Published 2013-01-01
    “…We establish some new Opial-type inequalities involving higher order delta derivatives on time scales. These extend some known results in the continuous case in the literature and provide new estimates in the setting of time scales.…”

    On the time-dependent parabolic wave equation by Arthur D. Gorman

    Published 2002-01-01
    “…Here we consider wave propagation in a restricted domain modelled by a parabolic wave equation whose properties vary both in space and in time. We develop a Wentzel-Kramers-Brillouin (WKB) formalism to obtain the asymptotic solution in noncaustic regions and modify the Lagrange manifold formalism to obtain the asymptotic solution near caustics. …”
