On Riemannian manifolds endowed with a locally conformal cosymplectic structure
International Journal of Mathematics and Mathematical Sciences, 2005 We deal with a locally conformal cosymplectic manifold M(φ,Ω,ξ,η,g) admitting a conformal contact quasi-torse-forming vector field T. The presymplectic 2-form Ω is a locally conformal cosymplectic 2-form.

Conformal embeddings and simple current extensions [PDF]
, 2014 In this paper we investigate the structure of intermediate vertex algebras associated with a maximal conformal embedding of a reductive Lie algebra in a semisimple Lie algebra of classical type.Comment: Latex file, 45 pages.

Parafermionic theory with the symmetry Z_5 [PDF]
, 2002 A parafermionic conformal theory with the symmetry Z_5 is constructed, based on the second solution of Fateev-Zamolodchikov for the corresponding parafermionic chiral algebra.

Conformal Lie algebras via deformation theory [PDF]
Journal of Mathematical Physics, 2019 We discuss possible notions of conformal Lie algebras, paying particular attention to graded conformal Lie algebras with d-dimensional space isotropy: namely, those with a co(d) subalgebra acting in a prescribed way on the additional generators. We classify those Lie algebras up to isomorphism for all d ⩾ 2 following the same methodology used recently ...

Loop Schrödinger–Virasoro Lie conformal algebra [PDF]
International Journal of Mathematics, 2016 In this paper, we introduce two kinds of Lie conformal algebras, associated with the loop Schrödinger–Virasoro Lie algebra and the extended loop Schrödinger–Virasoro Lie algebra, respectively. The conformal derivations, the second cohomology groups of these two conformal algebras are completely determined. And nontrivial free conformal modules of rank

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 ...

Poincare gauge gravity from nonmetric gravity
Nuclear Physics BWe consider general linear gauge theory, with independent solder form and connection. These spaces have both torsion and nonmetricity. We show that the Cartan structure equations together with the defining equation for nonmetricity allow the mixed ...
