Holographic Trace Anomaly and Local Renormalization Group
, 2015 The Hamilton-Jacobi method in holography has produced important results both at a renormalization group (RG) fixed point and away from it. In this paper we use the Hamilton-Jacobi method to compute the holographic trace anomaly for four- and six ...

A fast wavelet block Jacobi method
Journal of Mathematical Analysis and Applications, 2012 AbstractIn this paper, we develop a fast block Jacobi method for linear systems based on discrete wavelet transform (DWT). Traditional wavelet-based methods for linear systems do not fully utilize the sparsity and the multi-level block structure of the transformed matrix after DWT.

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics

Convergence of scaled iterates by the Jacobi method
Linear Algebra and its Applications, 2002 A quadratic convergence bound for scaled iterates by the serial Jacobi method for Hermitian positive definite matrices is derived. The bound is obtained in the general case of multiple eigenvalues.

A Jacobi–Davidson Method for Nonlinear Eigenproblems [PDF]
, 2004 For the nonlinear eigenvalue problem T(lambda)x = 0 we consider a Jacobi-Davidson type iterative projection method. The resulting projected nonlinear eigenvalue problems are solved by inverse iteration. The method is applied to a rational eigenvalue problem governing damped vibrations of a structure.

Different methods for the study of obstructions in the schemes of Jacobi [PDF]
Annales de l’institut Fourier, 2011 In this paper the problem of obstructions in Lie algebra deformations is studied from four different points of view. First, we illustrate the method of local ring, an alternative to Gerstenhaber’s method for Lie deformations. We draw parallels between both methods showing that an obstruction class corresponds to a nilpotent local parameter of a versal ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT The supercritical drive shaft is becoming increasingly popular in helicopter transmission system. Dry friction dampers are specially employed to ensure the supercritical shafts crossing the critical speed safely. Due to design tolerances, manufacturing errors and time‐varying factors, the parameters of the damper are inherently uncertain ...
