Identifiability of points and rigidity of hypergraphs under algebraic constraints
Journal of the London Mathematical Society, Volume 114, Issue 1, July 2026.Abstract The identifiability problem arises naturally in a number of contexts in mathematics and computer science. Specific instances include local or global rigidity of graphs and unique completability of partially‐filled tensors subject to rank conditions.

Elements of linear and multilinear algebra
, 2021 "This set of notes is an activity-oriented introduction to linear and multilinear algebra. The great majority of the most elementary results in these subjects are straightforward and can be verified by the thoughtful student.

Multilinear methods in linear algebra [PDF]
, 1991 Several classical and a few new results are presented in which multilinear algebra has proven to be an effective tool. Some of the topics covered are: Weyl's inequalities; the Hadamard product; mappings on tensor spaces; Gram matrices in tensor spaces ...

Fock space of local fields of the discrete GFF and its scaling limit bosonic CFT
Proceedings of the London Mathematical Society, Volume 133, Issue 1, July 2026.Abstract To connect conformal field theories (CFTs) to probabilistic lattice models, recent works of Hongler et al. and Adame‐Carrillo have introduced a novel definition of local fields of the lattice models. Local fields in this picture are probabilistically concrete: they are built from random variables in the model.

Finsler geometry on higher order tensor fields and applications to high angular resolution diffusion imaging. [PDF]
, 2009 We study 3D-multidirectional images, using Finsler geometry. The application considered here is in medical image analysis, specifically in High Angular Resolution Diffusion Imaging (HARDI) (Tuch et al. in Magn. Reson. Med.

On the Computation of Tensor Functions under Tensor‐Tensor Multiplications with Linear Maps
Numerical Linear Algebra with Applications, Volume 33, Issue 3, June 2026.ABSTRACT In this paper, we study the computation of both algebraic and non‐algebraic tensor functions under the tensor‐tensor multiplication with linear maps. In the case of algebraic tensor functions, we prove that the asymptotic exponent of both the tensor‐tensor multiplication and the tensor polynomial evaluation problem under this multiplication is

Red Blood Cell Membrane Mechanics Using Discrete Exterior Calculus (DEC) and Optimization
International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 4, April 2026.We present a novel DEC approach for calculating RBC shapes applicable to other cell types and membrane problems. We derive an energy minimization equation that can be solved semi‐implicitly, and a Lie derivative method to control node spacing. This novel work should aid computational modeling in many biological situations.

Fault Detection Analysis of State‐Triggered Impulsive Boolean Control Networks
IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.Based on the hybrid‐index model, we establish a time‐domain equivalent model for state‐triggered impulsive Boolean control networks (STIBCNs). In particular, the maximum jump matrix is introduced to characterise the system dynamics within the jumping subset.

FDA‐MIMO Range and Angle Estimation via Unitary CP Decomposition With Plug‐and‐Play Denoising
Electronics Letters, Volume 62, Issue 1, January/December 2026.ABSTRACT This letter proposes a joint data‐model‐driven framework for range and angle estimation. By integrating a unitary CP decomposition with a plug‐and‐play deep denoiser, we develop an iterative scheme that estimates factor matrices under the physical structural constraints and denoising priors.

Nonassociative constructions from inverse property quasigroups [PDF]
, 2011 PhDThe notion of a Hopf algebra has been generalized many times by weakening certain properties; we introduce Hopf quasigroups which weaken the associativity of the algebra.
