Abstract

This is the first in a series of papers in which we study vertex-algebraic structure of Feigin-Stoyanovsky's principal subspaces associated to standard modules for both untwisted and twisted affine Lie algebras. A key idea is to prove suitable presentations of principal subspaces, without using bases or even ``small'' spanning sets of these spaces. In this paper we prove presentations of the principal subspaces of the basic A_1^(1)-modules. These convenient presentations were previously used in work of Capparelli-Lepowsky-Milas for the purpose of obtaining the classical Rogers-Ramanujan recursion for the graded dimensions of the principal subspaces.

Polylogarithmic characterizations of the reduced coaction Lie algebra and the double shuffle Lie algebra, and their relation to the Kashiwara--Vergne Lie algebra

The reduced coaction Lie algebra $\mathfrak{rc}_0$ is defined by a skew-symmetric condition together with an algebraic equation involving the reduced coaction, a non-cyclic refinement of the necklace cobracket. The double shuffle Lie algebra $\mathfrak{dmr}_0$ encodes the regularized double shuffle relations in the study of formal multiple zeta values, while the Kashiwara--Vergne Lie algebra $\mathfrak{krv}_2$ arose in the study of the Kashiwara--Vergne conjecture. Our main result is the description of $\mathfrak{dmr}_0$ and $\mathfrak{rc}_0$ by vanishing conditions of different strengths on the same object: the defect of Drinfeld's pentagon equation; $\mathfrak{dmr}_0$ is characterised by the vanishing of the associated two-variable multiple polylogarithms, and $\mathfrak{rc}_0$ by the vanishing of those whose second index has depth $1$. We also establish explicit relations among these three Lie algebras. First, the skew-symmetric elements of $\mathfrak{dmr}_0$ embed into $\mathfrak{rc}_0$. Second, under an additional condition, we construct an injective Lie algebra morphism from $\mathfrak{rc}_0$ to $\mathfrak{krv}_2$.

Graded Necklace Lie Bialgebras and Batalin-Vilkovisky Formalism

An involutive Lie bialgebra induces a Batalin-Vilkovisky operator on its exterior algebra. We introduce a graded generalization of the necklace Lie bialgebra, which depends on a choice of a quiver $Q$. We relate the resulting Batalin-Vilkovisky structure to the Batalin-Vilkovisky structure coming from a degree $-1$ symplectic form on a suitably defined representation variety of the quiver $Q$. The morphism intertwining these Batalin-Vilkovisky algebras will be given by a twisted trace, recovering the usual (super)trace and the odd trace.

Freeness and divisibility for right $H$-simple left $H$-comodule algebras over a pointed Hopf algebra $H$

Let $H$ be a pointed Hopf algebra and let $A$ be a right $H$-simple left $H$-comodule algebra. We show that every relative $(H,A)$-Hopf module is free as an $A$-module and that this freeness characterizes the class of pointed Hopf algebras. We give a criterion for the category of relative $(H,A)$-Hopf modules to be semisimple. We also show that $A$ can be embedded into a left $H$-comodule algebra of a specific form when $H$ and $A$ are $\mathbb{N}_0$-graded. As a consequence, we prove that if $H$ is finite-dimensional and $A^{\mathrm{co} H}=\Bbbk$, then $A$ is finite-dimensional and $\dim A$ divides $\dim H$.
