On the convergence of the cyclic Jacobi method

Linear Algebra and its Applications, 1975
AbstractIn this paper we develop a class of cyclic orderings and prove that the cyclic Jacobi method using any cyclic ordering from this class converges to the eigensystem of a symmetric matrix.

Teardrop and heart orbits of a swinging Atwood's Machine

, 1993
An exact solution is presented for a swinging Atwood's machine. This teardrop-heart orbit is constructed using Hamilton-Jacobi theory. The example nicely illustrates the utility of the Hamilton-Jacobi method for finding solutions to nonlinear mechanical ...

Recurrence Relations of the Multi-Indexed Orthogonal Polynomials : III [PDF]

, 2016
In a previous paper, we presented conjectures of the recurrence relations with constant coefficients for the multi-indexed orthogonal polynomials of Laguerre, Jacobi, Wilson and Askey-Wilson types.

Spin‐Orbit Angular Momentum Conversion in Coupled Nonparaxial Bessel Acoustic Vortices

Advanced Science, EarlyView.
This study gives a formulaic description of the spin‐orbit angular momentum (AM) conversion in coupled fields of two nonparaxial Bessel acoustic vortices. Experimental results of wave field measurements provide compelling evidence for spin‐orbit AM conversion via passive artificial structures.

Application of Jacobi stability analysis to a first-order dynamical system: relation between nonlinearizability of one-dimensional differential equation and Jacobi stable region

Journal of Physics Communications
In this study, we discuss Jacobi stability in equilibrium and nonequilibrium regions for a first-order one-dimensional system using deviation curvatures.

On Generalizations of Jacobi–Jordan Algebras

Axioms
In this paper, we present some generalizations of Jacobi–Jordan algebras. More concretely, we will focus on noncommutative Jacobi–Jordan algebras, Malcev–Jordan algebras, and general Jacobi–Jordan algebras.

Cosmological perturbations in FRW model with scalar field within Hamilton-Jacobi formalism and symplectic projector method

, 2006
The Hamilton-Jacobi analysis is applied to the dynamics of the scalar fluctuations about the Friedmann-Robertson-Walker (FRW). The gauge conditions are found from the consistency conditions.

Analytical Approximation Methods for the Stabilizing Solution of the Hamilton–Jacobi Equation [PDF]

, 2007
In this paper, two methods for approximating the stabilizing solution of the Hamilton–Jacobi equation are proposed using symplectic geometry and a Hamiltonian perturbation technique as well as stable manifold theory.
