A Chebyshev–Halley Method with Gradient Regularization and an Improved Convergence Rate
High-order methods are particularly crucial for achieving highly accurate solutions or satisfying high-order optimality conditions. However, most existing high-order methods require solving complex high-order Taylor polynomial models, which pose ...

Efficient subspace iteration with Chebyshev-type filtering
Shift-invert and other methods for computing inner eigenvalues often require the solution of linear systems. This may become a problem if the linear systems are very ill-conditioned and the matrix dimension precludes the use of direct solvers. Then eigensolvers with polynomial acceleration become particularly attractive because they avoid the solution ...

Consensus acceleration in multi-agent systems with the Chebyshev semi-iterative method
We consider the fundamental problem of reaching consensus in multiagent systems. To date, the consensus problem has been typically solved with decentralized algorithms based on graph Laplacians. However, the convergence of these algorithms is often too slow for many important multiagent applications, and thus they are increasingly being combined with ...

A new iterative non-overlapping domain decomposition method is proposed for solving the one- and two-dimensional Helmholtz equation on parallel computers. The spectral collocation method is applied to solve the Helmholtz equation in each subdomain based

The Mixed Finite Element Multigrid Preconditioned MINRES Method for Stokes Equations
The study considers the saddle point problem arising from the mixed finite element discretization of the steady state Stokes equations. The saddle point problem is an indefinite system of linear equations, a feature that degrades the performance of any
