USp(2k) Matrix Model: Schwinger-Dyson Equations and Closed-Open String Interactions [PDF]
, 1998 We derive the Schwinger-Dyson/loop equations for the USp(2k) matrix model which close among the closed and open Wilson loop variables. These loop equations exhibit a complete set of the joining and splitting interactions required for the nonorientable ...

Journal of Inequalities and Applications, 2016 In this paper, we consider a class of weakly nonlinear complementarity problems (WNCP) with large sparse matrix. We present an accelerated modulus-based matrix splitting algorithm by reformulating the WNCP as implicit fixed point equations based on two ...

Accelerated normal and skew-Hermitian splitting methods for positive definite linear systems [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2013 For solving large sparse non-Hermitian positive definite linear equations, Bai et al. proposed the Hermitian and skew-Hermitian splitting methods (HSS). They recently generalized this technique to the normal and skew-Hermitian splitting methods (NSS). In

A Parameterized Multi-Splitting Iterative Method for Solving the PageRank Problem
Mathematics, 2023 In this paper, a new multi-parameter iterative algorithm is proposed to address the PageRank problem based on the multi-splitting iteration method. The proposed method solves two linear subsystems at each iteration by splitting the coefficient matrix ...

Unifying time evolution and optimization with matrix product states [PDF]
, 2015 We show that the time-dependent variational principle provides a unifying framework for time-evolution methods and optimisation methods in the context of matrix product states.

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.

Measurements of strongly-anisotropic g-factors for spins in single quantum states
, 2002 We have measured the full angular dependence, as a function of the direction of magnetic field, for the Zeeman splitting of individual energy states in copper nanoparticles. The g-factors for spin splitting are highly anisotropic, with angular variations
