Homotopy Transfer and Effective Field Theory II: Strings and Double Field Theory
Fortschritte der Physik, Volume 70, Issue 2-3, March 2022., 2022 Abstract We continue our study of effective field theory via homotopy transfer of L∞$L_\infty$‐algebras, and apply it to tree‐level non‐Wilsonian effective actions of the kind discussed by Sen in which the modes integrated out are comparable in mass to the modes that are kept. We focus on the construction of effective actions for string states at fixed

Higher-dimensional automorphic lie algebras [PDF]
, 2016 The paper presents the complete classification of Automorphic Lie Algebras based on sln(C)sln(C) , where the symmetry group G is finite and acts on sln(C)sln(C) by inner automorphisms, sln(C)sln(C) has no trivial summands, and where the poles are in ...

Restricted modules and associated vertex algebras of extended Heisenberg-Virasoro algebra [PDF]
, 2023 In this paper, a family of infinite dimensional Lie algebras $\tilde{\mathcal{L}}$ is introduced and investigated, called the extended Heisenberg-Virasoro algebra,denoted by $\tilde{\mathcal{L}}$.

Affine opers and conformal affine Toda
Journal of the London Mathematical Society, Volume 104, Issue 5, Page 2148-2207, December 2021., 2021 Abstract For g a Kac–Moody algebra of affine type, we show that there is an AutO‐equivariant identification between FunOpg(D), the algebra of functions on the space of g‐opers on the disc, and W⊂π0, the intersection of kernels of screenings inside a vacuum Fock module π0.

Pseudo-differential equations, and the Bethe ansatz for the classical Lie algebras [PDF]
, 2007 The correspondence between ordinary differential equations and Bethe ansatz equations for integrable lattice models in their continuum limits is generalised to vertex models related to classical simple Lie algebras.

Supersymmetric SYK model with global symmetry
Journal of High Energy Physics, 2018 In this paper, we introduce an N=1 $$ \mathcal{N}=1 $$ supersymmetric SYK model with SO(q) global symmetry. We study the large N expansion of the bi-local collective action of our model.

Weight modules for map (super)algebra related to the Virasoro algebra
, 2020 We classify Jet modules for the Lie (super)algebras $\mathfrak{L}=W\ltimes(\mathfrak{g}\otimes\mathbb{C}[t,t^{-1}])$, where $W$ is the Witt algebra and $\mathfrak{g}$ is a Lie superalgebra with an even diagonlizable derivation. Then we give a concept method to classify all simple cuspidal modules for $\mathfrak{L}$ and the map superalgebras, which are ...

Twisted Heisenberg-Virasoro vertex operator algebra [PDF]
, 2019 In this paper, we study a new kind of vertex operator algebras related to twisted Heisenberg-Virasoro algebra. We showed that there exist one-to-one correspondences between the restricted module categories of twisted Heisenberg-Virasoro algebras of rank ...

The generalized Davey-Stewartson equations, its Kac-Moody-Virasoro symmetry algebra and relation to DS equations [PDF]
Journal of Mathematical Physics, 2006 We compute the Lie symmetry algebra of the generalized Davey-Stewartson (GDS) equations and show that under certain conditions imposed on parameters in the system it is infinite-dimensional and isomorphic to that of the standard integrable Davey-Stewartson equations which is known to have a very specific Kac-Moody-Virasoro loop algebra structure.
