On Z2-twisted representation of vertex operator superalgebras and the Ising model SVOA
نویسنده
چکیده
We investigate a general theory of the Z2-twisted representations of vertex operator superalgebras. Certain one-to-one correspondence theorems are established. We also give an explicit realization of the Ising model SVOA and its Z2-twisted modules. As an application, we obtain the Gerald Höhn’s Babymonster SVOA VB♮ and its Z2-twisted module VB ♮ tw from the moonshine VOA V ♮ by cutting off the Ising models. It is also shown in this paper that Aut(VB♮) is finite.

Local Systems of Twisted Vertex Operators, Vertex Operator Superalgebras and Twisted Modules
We introduce the notion of “local system of ZT -twisted vertex operators” on a Z2-graded vector space M , generalizing the notion of local system of vertex operators [Li]. First, we prove that any local system of ZT -twisted vertex operators on M has a vertex superalgebra structure with an automorphism σ of order T with M as a σ-twisted module. Then we prove that for a vertex (operator) superal...
متن کاملTwisted Representation Rings and Dirac Induction
Extending ideas of twisted equivariant K-theory, we construct twisted versions of the representation rings for Lie superalgebras and Lie supergroups, built from projective Z2-graded representations with a given cocycle. We then investigate the pullback and pushforward maps on these representation rings (and their completions) associated to homomorphisms of Lie superalgebras and Lie supergroups....
متن کاملA Four-Reggeon Vertex for Z3 Twisted Fermionic Fields
Using operator sewing techniques we construct the Reggeon vertex involving four external Z3-twisted complex fermionic fields. Generalizing a procedure recently applied to the ordinary Ramond four-vertex, we deduce the closed form of the Z3 vertex by demanding it to reproduce the results obtained by sewing.

متن کاملOn vertex balance index set of some graphs
Let Z2 = {0, 1} and G = (V ,E) be a graph. A labeling f : V → Z2 induces an edge labeling f* : E →Z2 defined by f*(uv) = f(u).f (v). For i ε Z2 let vf (i) = v(i) = card{v ε V : f(v) = i} and ef (i) = e(i) = {e ε E : f*(e) = i}. A labeling f is said to be Vertex-friendly if | v(0) − v(1) |≤ 1. The vertex balance index set is defined by {| ef (0) − ef (1) | : f is vertex-friendly}. In this paper ...
متن کاملIntegrable Lattice Realizations of Conformal Twisted Boundary Conditions
We construct integrable lattice realizations of conformal twisted boundary conditions for ŝl(2) unitary minimal models on a torus. These conformal field theories are realized as the continuum scaling limit of critical A-D-E lattice models with positive spectral parameter. The integrable seam boundary conditions are labelled by (r, s, ζ) ∈ (Ag−2, Ag−1,Γ) where Γ is the group of automorphisms of ...
