Hamiltonian structure of Hamiltonian chaos [PDF]
Physics Letters A, 1997 From a kinematical point of view, the geometrical information of hamiltonian chaos is given by the (un)stable directions, while the dynamical information is given by the Lyapunov exponents.

Real Hamiltonian forms of Hamiltonian systems [PDF]
The European Physical Journal B, 2003 We introduce the notion of a real form of a Hamiltonian dynamical system in analogy with the notion of real forms for simple Lie algebras. This is done by restricting the complexified initial dynamical system to the fixed point set of a given involution.

A Theoretical Mechanism for the Action of SONG-Modulated Laser Light on Human Very Small Embryonic-Like (hVSEL) Stem Cells in Platelet Rich Plasma (PRP) [PDF]
CellR4, 2021 It has previously been shown that human very small embryonic-like (hVSEL) stem cell proliferation occurs rapidly when hVSEL stem cells in platelet rich plasma (PRP) are exposed to Strachan Ovokaitys Node Generator (SONG)-modulated laser light.

Analytical results for phase bunching in the pendulum model of wave-particle interactions
Frontiers in Astronomy and Space Sciences, 2022 Radiation belt electrons are strongly affected by resonant interactions with cyclotron-resonant waves. In the case of a particle passing through resonance with a single, coherent wave, a Hamiltonian formulation is advantageous.

Symmetry Transformation Parameters as Classical Dynamic Variables in the Gauge Theory
St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2020 A modification of the gauge theory is proposed, in which the set of generalized coordinates is supplemented with symmetry transformation parameters, and the condition is additionally imposed on the latter, which ensures the classical character of their ...

Distribution of energy in propagation for ocean extreme wave generation in hydrodynamics laboratory [PDF]
Global Journal of Environmental Science and Management, 2021 BACKGROUND AND OBJECTIVES: The hydrodynamic uncertainty of the ocean is the reason for testing marine structures as an initial consideration. This uncertainty has an impact on the natural structure of the topography as well as marine habitats.

Ricci curvature of semi-slant warped product submanifolds in generalized complex space forms
AIMS Mathematics, 2022 The objective of this paper is to achieve the inequality for Ricci curvature of a semi-slant warped product submanifold isometrically immersed in a generalized complex space form admitting a nearly Kaehler structure in the expressions of the squared norm

Reducibility for a class of almost periodic Hamiltonian systems which are degenerate
AIMS Mathematics, 2023 This paper studies the reducibility for a class of Hamiltonian almost periodic systems that are degenerate in a small perturbation parameter. We prove for most of the sufficiently small parameter, the Hamiltonian system is reducible by a symplectic ...
