A Matrix Splitting Perspective on Planning with Options
CoRR, 2016 We show that the Bellman operator underlying the options framework leads to a matrix splitting, an approach traditionally used to speed up convergence of iterative solvers for large linear systems of equations. Based on standard comparison theorems for matrix splittings, we then show how the asymptotic rate of convergence varies as a function of the ...

Splitting the spectral flow and the Alexander matrix
Commentarii Mathematici Helvetici, 1994 This paper studies the problem of computing the spectral flow \(\text{SF} (\alpha, \beta)\) of the Atiyah-Patodi-Singer operator between two flat SU(2)-connexions \(\alpha, \beta\) on a 3-manifold \(Z\), when \(Z\) is split along a torus so that \(\alpha,\beta\) can be connected by a path of flat connexions on each piece.

On the convergence of two-step modulus-based matrix splitting iteration method
Open Mathematics, 2021 In this paper, based on the relationship between the linear complementarity problem and its reformulated fixed-point equation, we discuss the conditions of the modulus-based type iteration methods. Moreover, we present some convergence results on the two-

Electron tunneling in the germanium/silicon heterostructure with germanium quantum dots: theory
Хімія, фізика та технологія поверхні, 2021 It is shown that electron tunneling through a potential barrier that separates two quantum dots of germanium leads to the splitting of electron states localized over spherical interfaces (a quantum dot – a silicon matrix).

A Matrix Splitting Method for Composite Function Minimization [PDF]
2017 IEEE Conference on Computer Vision and Pattern Recognition (CVPR), 2017 Composite function minimization captures a wide spectrum of applications in both computer vision and machine learning. It includes bound constrained optimization and cardinality regularized optimization as special cases. This paper proposes and analyzes a new Matrix Splitting Method (MSM) for minimizing composite functions.

A relaxed block splitting preconditioner for complex symmetric indefinite linear systems
Open Mathematics, 2018 In this paper, we propose a relaxed block splitting preconditioner for a class of complex symmetric indefinite linear systems to accelerate the convergence rate of the Krylov subspace iteration method and the relaxed preconditioner is much closer to the ...

IEEE Access, 2019 Splitting and combination are two important events of group target motion. However, the existing tracking approaches for group target splitting and combination events suffer the problems of high-computational cost and low accuracy.
