Cyclic Coset Orbifolds
We apply the new orbifold duality transformations to discuss the special case of cyclic coset orbifolds in further detail. We focus in particular on the case of the interacting cyclic coset orbifolds, whose untwisted sectors are Zλ(permutation)-invariant g/h coset constructions which are not λ copies of coset constructions. Because λ copies are not involved, the action of Zλ(permutation) in the...
متن کاملSystematic Approach to Cyclic Orbifolds
We introduce an orbifold induction procedure which provides a systematic construction of cyclic orbifolds, including their twisted sectors. The procedure gives counterparts in the orbifold theory of all the current-algebraic constructions of conformal field theory and enables us to find the orbifold characters and their modular transformation properties.
متن کاملGeometrization of 3-orbifolds of Cyclic Type
A 3-dimensional orbifold is a metrizable space with coherent local models given by quotients of R by finite subgroups of O(3). For example, the quotient of a 3-manifold by a properly discontinuous group action naturally inherits a structure of a 3-orbifold. Such an orbifold is said to be very good when the group action is finite. For a general background about orbifolds see [BS1,2], [DaM], [Sc]...
متن کاملClassification of coset-preserving skew-morphisms of finite cyclic groups
The concept of a coset-preserving skew-morphism is a generalization of the widely studied t-balanced skew-morphisms of regular Cayley maps which are in turn generalizations of group automorphisms. In case of abelian groups, all skew-morphisms of regular Cayley maps are roots of coset-preserving skew-morphisms, and therefore, classification of cosetpreserving skew-morphisms of finite abelian gro...
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 ...
