Intrinsic Quantization of Linear Hamiltonian Systems [PDF]

open access: yesEntropy
This article discusses the quantization of linear Hamiltonian systems, a historically rich but under explored line of research. The key idea is that a classical linear Hamiltonian system induces on its phase space a compatible complex structure and ...

On stability of motion of satellite [PDF]

open access: yesE3S Web of Conferences, 2023
In this paper we consider the translational and rotational motion of satellites around the Earth. First, we study the motion of an arrow-type satellite. We consider the system of equations of motion in the first approximation.

On stability of motion of unbalanced gyroscope [PDF]

open access: yesE3S Web of Conferences, 2023
In this paper we consider the stability of motion of an unbalanced gyroscope with a flexible shaft in gimbal suspension.Gyroscopes are used to control the stability of boom tower cranes.

Limit cycles of planar piecewise linear Hamiltonian differential systems with two or three zones

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2022
In this paper, we study the existence of limit cycles in continuous and discontinuous planar piecewise linear Hamiltonian differential system with two or three zones separated by straight lines and such that the linear systems that define the piecewise ...

Combining finite element space-discretizations with symplectic time-marching schemes for linear Hamiltonian systems

open access: yesFrontiers in Applied Mathematics and Statistics, 2023
We provide a short introduction to the devising of a special type of methods for numerically approximating the solution of Hamiltonian partial differential equations.

Extending Complex Conjugate Control to Nonlinear Wave Energy Converters

open access: yesJournal of Marine Science and Engineering, 2020
This paper extends the concept of Complex Conjugate Control (CCC) of linear wave energy converters (WECs) to nonlinear WECs by designing optimal limit cycles with Hamiltonian Surface Shaping and Power Flow Control (HSSPFC).

Index theory and multiple solutions for asymptotically linear second-order delay differential equations

open access: yesBoundary Value Problems, 2023
This paper is concerned with the existence of periodic solutions for asymptotically linear second-order delay differential equations. We will establish an index theory for the linear system directly in the sense that we do not need to change the problem ...

On the Derivation of Multisymplectic Variational Integrators for Hyperbolic PDEs Using Exponential Functions

open access: yesApplied Sciences, 2021
We investigated the derivation of numerical methods for solving partial differential equations, focusing on those that preserve physical properties of Hamiltonian systems.

On the Reducibility of Quasiperiodic Linear Hamiltonian Systems and Its Applications in Schrödinger Equation

open access: yesJournal of Function Spaces, 2020
In this paper, we consider the reducibility of the quasiperiodic linear Hamiltonian system ẋ=A+εQt, where A is a constant matrix with possible multiple eigenvalues, Qt is analytic quasiperiodic with respect to t, and ε is a small parameter.

Antiprincipal solutions at infinity for symplectic systems on time scales

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2020
In this paper we introduce a new concept of antiprincipal solutions at infinity for symplectic systems on time scales. This concept complements the earlier notion of principal solutions at infinity for these systems by the second author and Šepitka ...
