A Generalization of QR Factorization To Non-Euclidean Norms

CoRR, 2021
I propose a way to use non-Euclidean norms to formulate a QR-like factorization which can unlock interesting and potentially useful properties of non-Euclidean norms - for example the ability of $l^1$ norm to suppresss outliers or promote sparsity. A classic QR factorization of a matrix $\mathbf{A}$ computes an upper triangular matrix $\mathbf{R}$ and ...

Dynamic Current Routing in Conductive Liquid Crystal Elastomers for Complex Deformation Actuators

Advanced Materials Technologies, EarlyView.
This work introduces a novel actuation control strategy in which electrical stimulation generates localized Joule heating in conductive liquid crystal elastomer (LCE) surfaces, enabling complex 3D deformations from a single homogeneous surface without preprogramming.

On some properties of k-circulant matrices with the generalized Pell-Padovan numbers

Journal of Innovative Applied Mathematics and Computational Sciences
In this paper, we investigate the properties of the $k$-circulant matrix generated by the generalized Pell--Padovan numbers. We derive explicit formulas for the sum of entries, the maximum column sum norm ($\Vert \cdot \Vert _{1}$), the maximum row sum ...

On submultiplicative constants of an algebra

Journal of Inequalities and Applications, 2019
If A $\mathcal{A}$ is a finite-dimensional commutative associative real algebra with norm ∥⋅∥ $\| \cdot\|$ then we say that the rth submultiplicative constant of A $\mathcal{A}$ is the smallest constant mr(A) $m_{r}(\mathcal{A})$ for which ∥x1x2⋯xr∥≤mr(A)

Formation Control of Multi‐Agent System with Local Interaction and Artificial Potential Field

Advanced Robotics Research, EarlyView.
This article proposes a local interaction‐based formation control method for Multi‐Agent system, integrating consensus and leader‐follower strategies with a stress response mechanism—artificial potential field to reduce communication overhead and enable obstacle avoidance. Experimental results on triangular, square, and hexagonal formations confirm its

Stability of Covariant Relativistic Quantum Theory

, 2004
In this paper we study the relativistic quantum mechanical interpretation of the solution of the inhomogeneous Euclidean Bethe-Salpeter equation. Our goal is to determine conditions on the input to the Euclidean Bethe-Salpeter equation so the solution ...

Upper bounds for the Euclidean distances between the BLUPs

Special Matrices, 2018
In this article we consider the general linear model {y, X ß, V} where y is the observable random vector with expectation X ß and covariance matrix V. Our interest is on predicting the unobservable random vector y* which comes from y* = X* ß + ƹ* where ...

State/Operator Correspondence in Higher-Spin dS/CFT

, 2012
A recently conjectured microscopic realization of the dS$_4$/CFT$_3$ correspondence relating Vasiliev's higher-spin gravity on dS$_4$ to a Euclidean $Sp(N)$ CFT$_3$ is used to illuminate some previously inaccessible aspects of the dS/CFT dictionary.

Identifying Physical Interactions in Contact‐Based Robot Manipulation for Learning from Demonstration

Advanced Robotics Research, EarlyView.
Robots can learn manipulation tasks from human demonstrations. This work proposes a versatile method to identify the physical interactions that occur in a demonstration, such as sequences of different contacts and interactions with mechanical constraints.
