A natural construction of Borcherds' Fake Baby Monster Lie Algebra
Gerald Hoehn, Nils R. Scheithauer
We use a Z_2-orbifold of the vertex operator algebra associated to the Niemeier lattice with root lattice A_3^8 and the no-ghost theorem of string theory to construct a generalized…
Twisting the fake monster superalgebra
Nils R. Scheithauer
We calculate twisted denominator identities of the fake monster superalgebra and use them to construct new examples of supersymmetric generalized Kac-Moody superalgebras. Their den…
The fake monster superalgebra
Nils R. Scheithauer
We show that the physical states of a 10 dimensional superstring moving on a torus form a generalized Kac-Moody superalgebra. This gives the first explicit realizations of these al…
Vertex Algebras, Lie Algebras and Superstrings
Nils R. Scheithauer
Certain vertex algebras and Lie algebras arising in superstring theory are investigated. We show that the Fock space of a compactified Neveu-Schwarz superstring, i.e. a Neveu-Schwa…
