Higher representation stability for ordered configuration spaces
Journal of Topology, Volume 19, Issue 3, September 2026.Abstract Using factorization homology with coefficients in twisted commutative algebras (TCAs), we prove two flavors of higher representation stability for the cohomology of (generalized) configuration spaces of a scheme/topological space X$X$. First, we provide an iterative procedure to study higher representation stability using actions coming from ...

Partitioned Balancing Domain Decomposition Method for Heterogeneous Static Structures
International Journal for Numerical Methods in Engineering, Volume 127, Issue 16, 30 August 2026.ABSTRACT This study proposes a partitioned balancing domain decomposition (P‐BDD) method for static analysis of heterogeneous structures. The P‐BDD method may be viewed as a localized version of traditional BDD approaches. Its principal solution vector consists of unassembled partition‐boundary displacements, used to compute the partition‐interior ...

The Electronic Journal of Linear Algebra, 2009 As is well known, the Schur complements of strictly or irreducibly diagonally dominant matrices are H−matrices; however, the same is not true of generally diagonally dominant matrices. This paper proposes some conditions on the generally diagonally dominant matrix A and the subset α ⊂{ 1,2,...,n} so that the Schur complement matrix A/α is an H−matrix ...

, 2022 An $S$-ring (Schur ring) is called central if it is contained in the center of the group ring. We introduce the notion of a generalized Schur group, i.e. such finite group that all central $S$-rings over this group are schurian.

Some Schur complement identities and applications to matrix extrapolation methods [PDF]
, 2004 The Schur complement has many applications in linear algebra and in numerical analysis. Schur complement identities have been used for implementing some scalar and vector extrapolation methods. In this paper we define some matrix sequence transformations

Solution of RE Models with Anticipated Shocks and Optimal Policy [PDF]
The purpose of this paper is to solve linear dynamic rational expectations models with anticipated shocks by using the generalized Schur decomposition method. We also determine the optimal unrestricted and restricted policy responses to temporary as well
