A specialised cyclic reduction algorithm for linear algebraic equation systems with quasi-tridiagonal matrices

Journal of Mathematical Chemistry, 2017
Extensions have been developed, of several variants of the stride of two cyclic reduction method. The extensions refer to quasi-tridiagonal linear equation systems involving two additional nonzero elements in the first and last rows of the equation ...

Exponentiation Representation of Boolean Matrices in the Framework of Semi-Tensor Product of Matrices

IEEE Access, 2019
Semi-tensor product of matrices (STP of matrices) is a new matrix product and has been successfully applied to many fields, especially to logical dynamic systems.

Scattering of Sound Waves in Two Stepped Non-uniformly Lined Duct

Archives of Acoustics, 2020
Scattering of sound waves in two stepped cylindrical duct which walls are coated with different acoustically absorbent materials is investigated by using Wiener-Hopf technique directly and by determining scattering matrices.

Exact S-matrices for supersymmetric sigma models and the Potts model [PDF]

, 2002
We study the algebraic formulation of exact factorizable S-matrices for integrable two-dimensional field theories. We show that different formulations of the S-matrices for the Potts field theory are essentially equivalent, in the sense that they can be ...

New aspects of two Hessian-Riemannian metrics in plane [PDF]

Surveys in Mathematics and its Applications, 2020
Due to the importance of Hessian structures we express some algebraic and geo\-me\-tric features of two such semi-Riemannian metrics in dimension two. For this purpose we use the separable coordinate systems of the Euclidean plane. Several properties are

Dynamics of random Boolean networks under fully asynchronous stochastic update based on linear representation. [PDF]

PLoS ONE, 2013
A novel algebraic approach is proposed to study dynamics of asynchronous random Boolean networks where a random number of nodes can be updated at each time step (ARBNs). In this article, the logical equations of ARBNs are converted into the discrete-time

Symbolic algorithm for solving SLAEs with multi-diagonal coefficient matrices

Discrete and Continuous Models and Applied Computational Science
Systems of linear algebraic equations with multi-diagonal coefficient matrices may arise after many different scientific and engineering problems, as well as problems of the computational linear algebra where finding the solution of such a system of ...

Uniform convergence of V-cycle multigrid algorithms for two-dimensional fractional Feynman-Kac equation

, 2017
In this paper we derive new uniform convergence estimates for the V-cycle MGM applied to symmetric positive definite Toeplitz block tridiagonal matrices, by also discussing few connections with previous results. More concretely, the contributions of this

T-systems, Y-systems, and cluster algebras: Tamely laced case

, 2010
The T-systems and Y-systems are classes of algebraic relations originally associated with quantum affine algebras and Yangians. Recently they were generalized to quantum affinizations of quantum Kac-Moody algebras associated with a wide class of ...
