Wave asymptotics for waveguides and manifolds with infinite cylindrical ends

open access: yes, 2020
We describe wave decay rates associated to embedded resonances and spectral thresholds for waveguides and manifolds with infinite cylindrical ends. We show that if the cut-off resolvent is polynomially bounded at high energies, as is the case in certain ...

Modified Heisenberg Commutation Relations, Free Schrödinger Equations, Tunnel Effect and Its Connections with the Black–Scholes Equation

open access: yesAxioms
This paper explores the implications of modifying the canonical Heisenberg commutation relations over two simple systems, such as the free particle and the tunnel effect generated by a step-like potential.

Non-local Method of Improving Controls in the Linear Phase Variable Wave Problems

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2015
In this paper an optimal control problem with initial-boundary conditions is considered, where the relations between the control and the state vector are determined by the wave equation, which is linear with respect to the phase variable.
