Block ILU factorization preconditioners for a block-tridiagonal H-matrix

, 2000
We propose new parallelizable block ILU (incomplete LU) factorization preconditioners for a nonsymmetric block-tridiagonal H-matrix. Theoretical properties of these block ILU preconditioners are compared with those of block ILU preconditioners for the ...

Analytical Solution of the Symmetric Circulant Tridiagonal Linear System [PDF]

, 2014
A circulant tridiagonal system is a special type of Toeplitz system that appears in a variety of problems in scientific computation. In this paper we give a formula for the inverse of a symmetric circulant tridiagonal matrix as a product of a circulant ...

The Cyclic Odd-Even Reduction Method Applied in Mathematical Finance [PDF]

In this paper is presented a possibility to reduce execution time involved in evaluating a financial option by means finite difference scheme, using a cyclic odd-even reduction technique on a coarse-grained parallel model.coarse grained multicomputer ...

PT-symmetric Quantum Chain Models

Acta Polytechnica, 2007
A review is given of certain tridiagonal N-dimensional non-Hermitian J-parametric real-matrix quantum Hamiltonians H(N). The domains Ɗ(N) of reality of their spectra of energies are studied, with particular attention paid to their exceptional-point ...
