Conformal field theories with ZN and Lie algebra symmetries

Physics Letters B, 2004
We construct two-dimensional conformal field theories with a Z_N symmetry, based on the second solution of Fateev-Zamolodchikov for the parafermionic chiral algebra. Primary operators are classified according to their transformation properties under the dihedral group (Z_N x Z_2, where Z_2 stands for the Z_N charge conjugation), as singlets, [(N-1)/2 ...

Cosmology as a CFT1

Journal of High Energy Physics, 2019
We show that the simplest FLRW cosmological system consisting in the homo- geneous and isotropic massless Einstein-Scalar system enjoys a hidden conformal symmetry under the 1D conformal group SL(2, ℝ) acting as Mobius transformations in proper time ...

A Posteriori Estimates For A Coupled Piezoelectric Model With Uncertain Data

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 3, September 2026.
ABSTRACT The paper is concerned with a coupled piezo‐electric problem with incompletely known coefficients of the elasticity tensor and two other tensors that define electric properties of the media. Due to this uncertainty, the problem possesses a set (cloud) of equally probable solutions instead of a unique solution.

Filtered Lie conformal algebras whose associated graded algebras are isomorphic to that of general conformal algebra $gc_1$

Journal of Algebra, 2011
Let $G$ be a filtered Lie conformal algebra whose associated graded conformal algebra is isomorphic to that of general conformal algebra $gc_1$. In this paper, we prove that $G\cong gc_1$ or ${\rm gr\,}gc_1$ (the associated graded conformal algebra of $gc_1$), by making use of some results on the second cohomology groups of the conformal algebra $\fg ...

(2 + 1)-dimensional interacting model of two massless spin-2 fields as a bi-gravity model

Physics Letters B, 2018
We propose a new group-theoretical (Chern–Simons) formulation for the bi-metric theory of gravity in (2+1)-dimensional spacetime which describe two interacting massless spin-2 fields.

Nonlinear Force‐Extension Response of a Polyelectrolyte Chain Undergoing Mechano–Electrostatic–Conformational Coupling and Metastable Heterogeneity

Small Structures, Volume 7, Issue 9, September 2026.
Mechanical stretching drives a collapsed polyelectrolyte through globular, tadpole‐like, and extended conformations with concurrent charge redistribution. Counterion condensation neutralizes the compact head, whereas release sustains a highly ionized tail.

Finite irreducible modules of Lie conformal algebras 𝒲(a,b) and some Schrödinger–Virasoro type Lie conformal algebras

International Journal of Mathematics, 2019
Lie conformal algebras [Formula: see text] are the semi-direct sums of Virasoro Lie conformal algebra and its nontrivial conformal modules of rank one. In this paper, we first give a complete classification of all finite nontrivial irreducible conformal modules of [Formula: see text]. It is shown that all such modules are of rank one. Moreover, with a

Fermionic CFTs from topological boundaries in abelian Chern-Simons theories

Journal of High Energy Physics
A quantum field theory is referred to as bosonic (non-spin) if its physical quantities are independent of the spacetime spin structure, and as fermionic (spin) if they depend on it.

Effective When Distinctive: The Role of Phonetic Similarity in Nested Dependency Learning Across Preschool Years

Language Learning, Volume 76, Issue 3, Page 1027-1061, September 2026.
Abstract Parallel tracking of distant relations between speech elements, so‐called nonadjacent dependencies (NADs), is crucial in language development but computationally demanding and acquired only in late preschool years. As processing of single NADs is facilitated when dependent elements are perceptually similar, we investigated how phonetic ...

Invariant differential operators for non-compact Lie algebras parabolically related to conformal Lie algebras [PDF]

Journal of High Energy Physics, 2013
AbstractIn the present paper we continue the project of systematic construction of invariant differential operators for non-compact semisimple Lie groups. Our starting points is the class of algebras, which we call ’conformal Lie algebras’ (CLA), which have very similar properties to the conformal algebras of Minkowski space-time, though our aim is to ...
