متن کاملOrbifold Zhu’s theory associated to intertwining operators
We study intertwining operators among the twisted modules for rational VOAs and show the modular invariance property of the space spanned by the trace functions concerning to some representations of rational orbifold VOAs. Our result generalizes the results obtained in [DLM2] and [M3].
متن کاملHigher Order Couplings from Heterotic Orbifold Theory
We calculate couplings of arbitrary order from correlation functions among twisted strings, using conformal field theory. Twisted strings arise in heterotic string compactified on orbifolds yielding matter fields in the low energy limit. We calculate completely the classical and the quantum amplitude including normalization, up to a contribution from Kähler potential. The classical action has s...
متن کاملNew Duality Transformations in Orbifold Theory
We find new duality transformations which allow us to construct the stress tensors of all the twisted sectors of any orbifold A(H)/H, where A(H) is the set of all currentalgebraic conformal field theories with a finite symmetry group H ⊂ Aut(g). The permutation orbifolds with H = Zλ and H = S3 are worked out in full as illustrations but the general formalism includes both simple and semisimple ...
متن کاملWeighted Ehrhart Theory and Orbifold Cohomology
We introduce the notion of a weighted δ-vector of a lattice polytope. Although the definition is motivated by motivic integration, we study weighted δ-vectors from a combinatorial perspective. We present a version of Ehrhart Reciprocity and prove a change of variables formula. We deduce a new geometric interpretation of the coefficients of the Ehrhart δ-vector. More specifically, they are sums ...
