Product States of Infinite Tensor Product of JC-algebras
AxiomsThe objective of our study is to generalize the results on product states of the tensor product of two JC-algebras to infinite tensor product JC-algebras.

Representation Theory of Quantized Enveloping Algebras with Interpolating Real Structure
Symmetry, Integrability and Geometry: Methods and Applications, 2013 Let g be a compact simple Lie algebra. We modify the quantized enveloping ∗-algebra associated to g by a real-valued character on the positive part of the root lattice.

On the topological ranks of Banach ∗$^*$‐algebras associated with groups of subexponential growth
Bulletin of the London Mathematical Society, Volume 58, Issue 2, February 2026.Abstract Let G$G$ be a group of subexponential growth and C→qG$\mathcal C\overset{q}{\rightarrow }G$ a Fell bundle. We show that any Banach ∗$^*$‐algebra that sits between the associated ℓ1$\ell ^1$‐algebra ℓ1(G|C)$\ell ^1(G\,\vert \,\mathcal C)$ and its C∗$C^*$‐envelope has the same topological stable rank and real rank as ℓ1(G|C)$\ell ^1(G\,\vert ...

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.

The universal enveloping algebras of n-differential graded Poisson algebras(n次微分分次Poisson代数的泛包络代数)
Zhejiang Daxue xuebao. Lixue ban, 2016 给出了n次微分分次Poisson代数的泛包络代数的定义及相关性质，同时给出了它的应用，即e是n次微分Z-分次Poisson代数范畴到微分Z-分次代数范畴的一个共变函子和（Ae)op=（Aop）e，其中A是任意的n次微分分次Poisson代数.

Jordan homomorphisms and T‐ideals
Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.Abstract Let A$A$ and B$B$ be associative algebras over a field F$F$ with char(F)≠2${\rm char}(F)\ne 2$. Our first main result states that if A$A$ is unital and equal to its commutator ideal, then every Jordan epimorphism φ:A→B$\varphi:A\rightarrow B$ is the sum of a homomorphism and an antihomomorphism. Our second main result concerns (not necessarily

IET Control Theory &Applications, Volume 20, Issue 1, January/December 2026.The work delivers a rigorous mathematical framework for asymptotic tracking in nonlinear systems that explicitly include control‐input derivatives, actuator dynamics, and input saturation, with Lyapunov‐based proofs establishing convergence and robustness under their coupled effects.

Wreath products of cocommutative Hopf algebras [PDF]
, 2014 We define wreath products of cocommutative Hopf algebras, and show that they enjoy a universal property of classifying cleft extensions, analogous to the Kaloujnine-Krasner theorem for groups.

Matrix Freedman Inequality for Sub‐Weibull Martingales
Stat, Volume 14, Issue 4, December 2025.ABSTRACT In this paper, we establish a matrix Freedman inequality for martingales with sub‐Weibull tails. Under conditional ψα$$ {\psi}_{\alpha } $$ control of the increments, the top eigenvalue admits a non‐asymptotic tail bound with explicit, dimension‐aware constants.
