On the Poincaré Polynomials for Landau-Ginzburg Orbifolds
نویسنده
چکیده
We construct the Poincaré polynomials for Landau-Ginzburg orbifolds with projection operators. Using them we show that special types of dualities including Poincaré duality are realized under certain conditions. When Calabi-Yau interpretation exists, two simple formulae for Hodge numbers h and h are obtained.

Exact solutions of the 2D Ginzburg-Landau equation by the first integral method
The first integral method is an efficient method for obtaining exact solutions of some nonlinear partial differential equations. This method can be applied to non integrable equations as well as to integrable ones. In this paper, the first integral method is used to construct exact solutions of the 2D Ginzburg-Landau equation.
متن کاملElliptic Genera and the Landau–Ginzburg Approach to N=2 Orbifolds
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 ...

We search for a Landau–Ginzburg interpretation of non-diagonal modular invariants of tensor products of minimal n = 2 superconformal models, looking in particular at automorphism invariants and at some exceptional cases. For the former we find a simple description as Landau–Ginzburg orbifolds, which reproduce the correct chiral rings as well as the spectra of various Gepner–type models and orbi...

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 کاملElliptic 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 ...
