Elliptic Genera and the Landau–Ginzburg Approach to N=2 Orbifolds
نویسنده
چکیده
We compute the elliptic genera of orbifolds associated with N = 2 super–conformal theories which admit a Landau-Ginzburg description. The identification of the elliptic genera of the macroscopic Landau-Ginzburg orbifolds with those of the corresponding microscopic N = 2 orbifolds further supports the conjectured identification of these theories. For SU(N) Kazama-Suzuki models the orbifolds are associated with certain ZZp subgroups of the various coset factors. Based on our approach we also conjecture the existence of ”E-type” variants of these theories, their elliptic genera and the corresponding LandauGinzburg potentials.

Elliptic genera of Landau-Ginzburg models over nontrivial spaces
In this paper, we discuss elliptic genera of (2,2) and (0,2) supersymmetric Landau-Ginzburg models over nontrivial spaces, i.e. nonlinear sigma models on nontrivial noncompact manifolds with superpotential, generalizing old computations in Landau-Ginzburg models over (orbifolds of) vector spaces. For Landau-Ginzburg models in the same universality class as nonlinear sigma models, we explicitly ...
متن کاملGeometry of (0,2) Landau-Ginzburg Orbifolds
Several aspects of (0,2) Landau-Ginzburg orbifolds are investigated. Especially the elliptic genera are computed in general and, for a class of models recently invented by Distler and Kachru, they are compared with the ones from (0,2) sigma models. Our formalism gives an easy way to calculate the generation numbers for lots of Distler-Kachru models even if they are based on singular Calabi-Yau ...
متن کاملSome new exact traveling wave solutions one dimensional modified complex Ginzburg- Landau equation
In this paper, we obtain exact solutions involving parameters of some nonlinear PDEs in mathmatical physics; namely the one-dimensional modified complex Ginzburg-Landau equation by using the $ (G'/G) $ expansion method, homogeneous balance method, extended F-expansion method. By using homogeneous balance principle and the extended F-expansion, more periodic wave solutions expressed by j...
متن کاملLandau-Ginzburg Orbifolds, Mirror Symmetry and the Elliptic Genus
We compute the elliptic genus for arbitrary two dimensional N = 2 Landau-Ginzburg orbifolds. This is used to search for possible mirror pairs of such models. We show that if two Landau-Ginzburg models are conjugate to each other in a certain sense, then to every orbifold of the first theory corresponds an orbifold of the second theory with the same elliptic genus (up to a sign) and with the rol...
متن کاملTwisted Elliptic Genera of N = 2 SCFTs in Two Dimensions
The elliptic genera of two-dimensional N = 2 superconformal field theories can be twisted by the action of the integral Heisenberg group if their U(1) charges are fractional. The basic properties of the resulting twisted elliptic genera and the associated twisted Witten indices are investigated with due attention to their behaviors in orbifoldization. Our findings are illustrated by and applied...
