T-branes at the limits of geometry

Journal of High Energy Physics, 2017
Singular limits of 6D F-theory compactifications are often captured by T-branes, namely a non-abelian configuration of intersecting 7-branes with a nilpotent matrix of normal deformations.

A Hilton–Milner theorem for exterior algebras

Transactions of the London Mathematical Society, Volume 12, Issue 1, December 2025.
Abstract Recent work of Scott and Wilmer and of Woodroofe extends the Erdős–Ko–Rado theorem from set systems to subspaces of k$k$‐forms in an exterior algebra. We prove an extension of the Hilton–Milner theorem to the exterior algebra setting, answering in a strong way a question asked by these authors.

A Characterization of Affine Primal Topological Spaces Induced by Nilpotent Matrices

International Journal of Mathematics and Mathematical Sciences
In this article, we prove that an n×n matrix A is nilpotent if and only if there exists an affine primal topology τ for Rn such that the space Rn,τ is both compact and connected.

On n-quasi- [m,C] $[m,C]$-isometric operators

Journal of Inequalities and Applications, 2019
For positive integers m and n, an operator T∈B(H) $T \in B ( H )$ is said to be an n-quasi- [m,C] $[m,C]$-isometric operator if there exists some conjugation C such that T∗n(∑j=0m(−1)j(mj)CTm−jC.Tm−j)Tn=0 . In this paper, some basic structural properties

Quick design of feasible tensor networks for constrained combinatorial optimization [PDF]

Quantum
Quantum computers are expected to enable fast solving of large-scale combinatorial optimization problems. However, their limitations in fidelity and the number of qubits prevent them from handling real-world problems.

Index reduction for rectangular descriptor systems via feedbacks

Cogent Engineering, 2017
Index plays a fundamental role in the study of descriptor systems. For regular descriptor systems, calculation of the index can be performed by calculating the index of the nilpotent matrix obtained by means of the Weierstrass canonical form ...

Computational Study of Fuzzy Neutrosophic Soft Matrices in Python: Consistency and Weak Transitivity [PDF]

Neutrosophic Sets and Systems
In this study, we introduce a novel framework for defining and analyzing two specific types of Fuzzy Neutrosophic Soft Matrices (FNSMs): consistent and weakly transitive.

On Nilpotent Elements and Armendariz Modules

Mathematics
For a left module MR over a non-commutative ring R, the notion for the class of nilpotent elements (nilR(M)) was first introduced and studied by Sevviiri and Groenewald in 2014 (Commun. Algebra, 42, 571–577).
