Row‐Aware Randomized SVD With Applications

Numerical Linear Algebra with Applications, Volume 33, Issue 3, June 2026.
ABSTRACT The randomized singular value decomposition proposed in [28] has certainly become one of the most well‐established randomization‐based algorithms in numerical linear algebra. The key ingredient of the entire procedure is the computation of a subspace which is close to the column space of the target matrix A∈ℝm×n$$ \mathbf{A}\in {\mathbb{R}}^{m\

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

Comparison of A‐Posteriori Error Estimators in the Context of Parametric Model Order Reduction by Matrix Interpolation

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT The use of parametric model order reduction (pMOR) by matrix interpolation enables efficient simulation of large‐scale finite element (FE) models in multi‐query applications such as optimization and uncertainty quantification. In this method, high‐fidelity systems are sampled, individually reduced by projection‐based model order reduction, and

Adaptability and Stability Analyses of Root Yield and Micronutrient Concentrations in Sweetpotato (Ipomoea batatas [L.] Lam.) Genotypes

Plant-Environment Interactions, Volume 7, Issue 3, June 2026.
ABSTRACT High yielding and micronutrient dense sweetpotato cultivars could contribute to alleviating micronutrient deficiency, which is a prevalent problem in developing countries. Developing these improved cultivars involves selection across diverse environments, which requires an understanding of genotype × environment interaction (GEI).
