Extensions of modules over a class of Lie conformal algebras đČ(b) [PDF]
Journal of Algebra and its Applications, 2018 Let [Formula: see text] be a class of free Lie conformal algebras of rank two with [Formula: see text]-basis [Formula: see text] and relations [Formula: see text] where [Formula: see text] is a nonzero complex number.

On finite representations of conformal algebras
, 2010 We prove a finite torsion-free associative conformal algebra to have a finite faithful conformal representation. As a corollary, it is shown that one may join a conformal unit to such an algebra.

Central extensions and conformal derivations of a class of Lie conformal algebras [PDF]
Linear and Multilinear Algebra, 2020 21 pages. We add some results on the central extensions of quadratic Lie conformal algebras by a one-dimensional center $\mathbb{C}\mathfrak{c}_\beta$ and an abelian Lie conformal algebra $\mathbb{C}[\partial]\mathfrak{c}$ which is free of rank ...

European Physical Journal C: Particles and Fields, 2018 By means of the Lie algebra expansion method, the centrally extended conformal algebra in two dimensions and the $$\mathfrak {bms}_{3}$$ bms3 algebra are obtained from the Virasoro algebra.

Freely Generated Vertex Algebras and Non?Linear Lie Conformal Algebras [PDF]
Communications in Mathematical Physics, 2005 We introduce the notion of a non--linear Lie conformal superalgebra and prove a PBW theorem for its universal enveloping vertex algebra. We also show that conversely any graded freely generated vertex algebra is the universal enveloping algebra of a non--linear Lie conformal superalgebra.

, 1997 $\Gamma$-conformal algebra is an axiomatic description of the operator product expansion of chiral fields with simple poles at finitely many points. We classify these algebras and their representations in terms of Lie algebras and their representations ...

Fullâorder observer design for quadratic portâcontrolled Hamiltonian systems
Asian Journal of Control, EarlyView.Abstract The fullâorder observer design problem for a particular class of portâcontrolled Hamiltonian systems is approached in this paper. The proposed fullâorder observer scheme belongs to the structure preserving class of dynamic estimators as it preserves the natural stability properties of the approached class of systems that are useful for the ...

Stereodynamism in Chiral Polyaromatic Phosphepines
Chemistry â A European Journal, EarlyView.Stereodynamism of phosphahelicenoid scaffolds can be used to afford diastereoisomers of polyaromatics fused with a chiral sevenâmembered Pâring. In particular, a complex interplay between the inversion at the P centre and helicenoid epimerization, as well as a competition with a rearomatization reaction, takes place.

Quadratic Lie conformal superalgebras related to Novikov superalgebras [PDF]
Journal of Noncommutative Geometry, 2019 We study quadratic Lie conformal superalgebras associated with No\-vikov superalgebras. For every Novikov superalgebra $(V,\circ)$, we construct an enveloping differential Poisson superalgebra $U(V)$ with a derivation $d$ such that $u\circ v = ud(v)$ and
