Bidiagonal Decompositions and Accurate Computations for the Ballot Table and the Fibonacci Matrix
Numerical Linear Algebra with Applications, Volume 33, Issue 1, February 2026.ABSTRACT Riordan arrays include many important examples of matrices. Here we consider the ballot table and the Fibonacci matrix. For finite truncations of these Riordan arrays, we obtain bidiagonal decompositions. Using them, algorithms to solve key linear algebra problems for ballot tables and Fibonacci matrices with high relative accuracy are derived.

$M$-ideals and quasi-triangular algebras
Illinois Journal of Mathematics, 1987 If \({\mathcal P}\) is a linearly ordered set of projections on a Hilbert space and \({\mathcal K}\) is the ideal of compact operators, then \(\text{Alg}\, {\mathcal P}+{\mathcal K}\) is the quasi-triangular algebra associated with \({\mathcal P}.\) We show that \((\text{Alg}\,{\mathcal P}+{\mathcal K})/\text{Alg}\,{\mathcal P}\) is an M-ideal in ...

Definition and Computation of Tensor‐Based Generalized Function Composition
Numerical Linear Algebra with Applications, Volume 33, Issue 1, February 2026.ABSTRACT Functions are fundamental to mathematics as they offer a structured and analytical framework to express relations between variables. While scalar and matrix‐based functions are well‐established, higher‐order tensor‐based functions have not been as extensively explored.

Forces in MechanicsThis paper presents a new co-rotational shell element based on quaternion algebra as a means of parameterizing large rotations. The co-rotational framework is suitable for beam or shell elements and has been extensively studied in the literature.

Differentiable River Routing for End‐to‐End Learning of Hydrological Processes
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 1, February 2026.Abstract Deep Learning (DL) approaches have shown high accuracy in rainfall runoff modeling. Currently, however, large‐scale DL hydrological simulations at national and global scales still rely on external routing schemes to propagate runoff outputs through river networks, preventing them from leveraging the benefits of end‐to‐end learning of ...

Journal of Computer Assisted Learning, Volume 42, Issue 1, February 2026.ABSTRACT Background Traditionally, combining individual and collaborative learning happens in a pre‐planned and synchronised manner where the whole class switches between activities at the same time. However, in an era where personalised learning is showing great promise, a more dynamic way of combining the two activities may lead to better learning ...
