Weakly Convex Ridge Regularization for 3D Non‐Cartesian MRI Reconstruction
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose While highly accelerated non‐Cartesian acquisition protocols significantly reduce scan time, they often entail long reconstruction delays for 3D data. Deep learning–based reconstruction methods can alleviate this, but typically rely on complex, highly parametrized architectures.

Structure of the Enveloping Algebras
Acta Polytechnica, 2007 The adjoint representations of several small dimensional Lie algebras on their universal enveloping algebras are explicitly decomposed. It is shown that commutants of raising operators are generated as polynomials in several basic elements.

Modular class of Lie $\infty$-algebroids and adjoint representation
, 2022 We study the modular class of $Q$-manifolds, and in particular of negatively graded Lie $\infty$-algebroid. We show the equivalence of several descriptions of those classes, that it matches the classes introduced by various authors and that the notion is homotopy invariant.

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This paper presents a Physics‐Informed Koopman Operator (PIKO) framework integrated with a discrete‐time Sequential Action Control (SAC) for real‐time, decentralized control of a modular aerial parcel delivery robot composed of multiple independently actuated propeller modules.

On the depth of the adjoint representations
Let $F$ be a non-archimedean local field of odd residual characteristic $p$. The depth of a smooth representation of ${\rm GL}_n(F)$ is an invariant of Local Langlands Correspondence (LLC). The analogous notion on the Galois side of LLC is known as the slope of a local Galois representation.

Exterior powers of the adjoint representation and the Weyl ring of E8 [PDF]
Journal of Algebra, 2020 I derive explicitly all polynomial relations in the character ring of $E_8$ of the form $χ_{\wedge^k \mathfrak{e}_8} - \mathfrak{p}_{k} (χ_{1}, \dots, χ_{8})=0$, where $\wedge^k \mathfrak{e}_8$ is an arbitrary exterior power of the adjoint representation and $χ_{i}$ is the $i^{\rm th}$ fundamental character.

A Gauss–Newton Method for ODE Optimal Tracking Control
Optimal Control Applications and Methods, EarlyView.This paper presents a Gauss–Newton method for optimal tracking control of ordinary differential equations (ODEs). The approach formulates the problem as an infinite‐dimensional optimization problem, allowing both control functions and uncertain model parameters to be optimized.

Novel families of SU(N) AKLT states with arbitrary self-conjugate edge states
Nuclear Physics B, 2019 Using the Matrix Product State framework, we generalize the Affleck-Kennedy-Lieb-Tasaki (AKLT) construction to one-dimensional spin liquids with global color SU(N) symmetry, finite correlation lengths, and edge states that can belong to any self ...

Adjoint Representations of the Symmetric Group
, 2018 We study the restriction to the symmetric group, $\mc{S}_n$ of the adjoint representation of $\mt{GL}_n(\C)$. We determine the irreducible constituents of the space of symmetric as well as the space of skew-symmetric $n\times n$ matrices as $\mc{S}_n$-modules.
