Lie bialgebra structures on the twisted Heisenberg–Virasoro algebra [PDF]

open access: yes, 2012
In this paper we investigate Lie bialgebra structures on the twisted Heisenberg–Virasoro algebra. With the determination of certain Lie bialgebra structures on the Virasoro algebra, we determine certain structures on the twisted Heisenberg–Virasoro ...

Framed Vertex Operator Algebras, Codes and the Moonshine Module [PDF]

open access: yes, 1998
For a simple vertex operator algebra whose Virasoro element is a sum of commutative Virasoro elements of central charge ½, two codes are introduced and studied. It is proved that such vertex operator algebras are rational.

Classification of finite irreducible conformal modules over some Lie conformal algebras related to the Virasoro conformal algebra [PDF]

open access: yesJournal of Mathematical Physics, 2017
In this paper, we classify all finite irreducible conformal modules over a class of Lie conformal algebras W(b) with b∈ℂ related to the Virasoro conformal algebra. Explicitly, any finite irreducible conformal module over W(b) is proved to be isomorphic to MΔ,α,β with Δ≠0 or β≠0 if b = 0, or MΔ,α with Δ≠0 if b≠0.

Fock space of local fields of the discrete GFF and its scaling limit bosonic CFT

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 1, July 2026.
Abstract To connect conformal field theories (CFTs) to probabilistic lattice models, recent works of Hongler et al. and Adame‐Carrillo have introduced a novel definition of local fields of the lattice models. Local fields in this picture are probabilistically concrete: they are built from random variables in the model.

Probabilistic correlation functions of the Schwarzian field theory

open access: yesProceedings of the London Mathematical Society, Volume 132, Issue 6, June 2026.
Abstract We study correlation functions of the probabilistic Schwarzian field theory. We compute cross‐ratio correlation functions exactly in the case when the corresponding Wilson lines do not intersect, confirming predictions made in the physics literature via limit of the conformal bootstrap and the DOZZ formula.

2‐Local Derivations on the Twisted Heisenberg–Virasoro Algebra

open access: yesAdvances in Mathematical Physics, Volume 2026, Issue 1, 2026.
2‐local derivation is a generalized derivation for a Lie algebra, which plays an important role to the study of local properties of the structure of the Lie algebra. In this article, we prove that every 2‐local derivation on the twisted Heisenberg–Virasoro algebra is a derivation. MSC2020 Classification 16E40, 17B56, 17B68.

Comments on the RG‐Flow in Open String Field Theory

open access: yesFortschritte der Physik, Volume 73, Issue 12, December 2025.
Abstract We define a metric G$G$ on the KBc‐subalgebra modulo gauge and describe the worldsheet RG‐flow as the gradient flow of the action of cubic open string field theory, where the flow lines are kink‐solitons. In particular, for a constant tachyon the gradient flow equations are equivalent to the RG‐equations. Additionally, a more general family of

W‐algebras, Gaussian free fields, and g$\mathfrak {g}$‐Dotsenko–Fateev integrals

open access: yesProceedings of the London Mathematical Society, Volume 131, Issue 6, December 2025.
Abstract Based on the intrinsic connection between Gaussian free fields and the Heisenberg vertex algebra, we study some aspects of the correspondence between probability theory and W$W$‐algebras. This is first achieved by providing a construction of the W$W$‐algebra associated to a complex simple Lie algebra g$\mathfrak {g}$ by means of Gaussian free ...

A class of equations with peakon and pulson solutions (with an Appendix by Harry Braden and John Byatt-Smith) [PDF]

open access: yes, 2005
We consider a family of integro-differential equations depending upon a parameter b as well as a symmetric integral kernel g(x). When b=2 and g is the peakon kernel (i.e.
