A FEAST SVDsolver Based on Chebyshev–Jackson Series for Computing Partial Singular Triplets of Large Matrices [PDF]

open access: yesJournal of Scientific Computing, 2022
The FEAST eigensolver is extended to the computation of the singular triplets of a large matrix A with the singular values in a given interval. The resulting FEAST SVDsolver is subspace iteration applied to an approximate spectral projector of $$A^TA$$ A

Optimal Chebyshev Smoothers and One-sided V-cycles [PDF]

open access: yesarXiv.org, 2022
The solution to the Poisson equation arising from the spectral element discretization of the incompressible Navier-Stokes equation requires robust preconditioning strategies. One such strategy is multigrid.

Chebyshev polynomial filtered subspace iteration in the discontinuous Galerkin method for large-scale electronic structure calculations. [PDF]

open access: yesJournal of Chemical Physics, 2016
The Discontinuous Galerkin (DG) electronic structure method employs an adaptive local basis (ALB) set to solve the Kohn-Sham equations of density functional theory in a discontinuous Galerkin framework. The adaptive local basis is generated on-the-fly to

Chebyshev Inertial Iteration for Accelerating Fixed-Point Iterations

open access: yes, 2020
A novel method which is called the Chebyshev inertial iteration for accelerating the convergence speed of fixed-point iterations is presented. The Chebyshev inertial iteration can be regarded as a valiant of the successive over relaxation or Krasnosel'ski\v -Mann iteration utilizing the inverse of roots of a Chebyshev polynomial as iteration dependent

Numerical Studies for Fractional-Order Logistic Differential Equation with Two Different Delays

open access: yesJournal of Applied Mathematics, 2012
A numerical method for solving the fractional-order logistic differential equation with two different delays (FOLE) is considered. The fractional derivative is described in the Caputo sense. The proposed method is based upon Chebyshev approximations. The
