Monstrous and Generalized Moonshine and Permutation Orbifolds
We consider the application of permutation orbifold constructions towards a new possible understanding of the genus zero property in Monstrous and Generalized Moonshine. We describe a theory of twisted Hecke operators in this setting and conjecture on the form of Generalized Moonshine replication formulas.
متن کاملSolitons in Affine and Permutation Orbifolds
We consider properties of solitons in general orbifolds in the algebraic quantum field theory framework and constructions of solitons in affine and permutation orbifolds. Under general conditions we show that our construction gives all the twisted representations of the fixed point subnet. This allows us to prove a number of conjectures: in the affine orbifold case we clarify the issue of “fixe...
متن کاملThe Orbifolds of Permutation-type as Physical String Systems at Multiples of C = 26 v. Cyclic Permutation Orbifolds
I consider the Z λ , λ prime free-bosonic permutation orbifolds as interacting physical string systems atˆc = 26λ. As a first step, I introduce twisted tree diagrams which confirm at the interacting level that the physical spectrum of each twisted sector is equivalent to that of an ordinary c = 26 closed string. The untwisted sectors are surprisingly more difficult to understand, and there are ...
متن کاملExtended Operator Algebra and Reducibility in the WZW Permutation Orbifolds
Recently the operator algebra, including the twisted affine primary fields, and a set of twisted KZ equations were given for the WZW permutation orbifolds. In the first part of this paper we extend this operator algebra to include the so-called orbifold Virasoro algebra of each WZW permutation orbifold. These algebras generalize the orbifold Virasoro algebras (twisted Virasoro operators) found ...
متن کاملThe torus and the Klein bottle amplitude of permutation orbifolds
The torus and the Klein bottle amplitude coefficients are computed in permutation orbifolds of RCFT-s in terms of the same quantities in the original theory and the twist group. An explicit expression is presented for the number of self conjugate primaries in the orbifold as a polynomial of the total number of primaries and the number of self conjugate ones in the parent theory. The formulae in...
