Generalized Rogers Ramanujan Identities from AGT Correspondence
AGT correspondence and its generalizations attracted a great deal of
attention recently. In particular it was suggested that instantons on
describe the conformal blocks of the coset , where is a
parameter. Our purpose here is to describe Generalized Rogers Ramanujan (GRR)
identities for these cosets, which expresses the characters as certain
series. We propose that such identities exist for the coset for
all positive integers and all and . We treat here the case of
and , finding GRR identities for all the characters.Comment: 11 page
Special geometry on the 101 dimesional moduli space of the quintic threefold
A new method for explicit computation of the CY moduli space metric was
proposed by the authors recently. The method makes use of the connection of the
moduli space with a certain Frobenius algebra. Here we clarify this approach
and demonstrate its efficiency by computing the Special geometry of the
101-dimensional moduli space of the quintic threefold around the orbifold
point.Comment: We made exposition more clear, in particular we explained how to
generalize our idea
Special geometry on the moduli space for the two-moduli non-Fermat Calabi-Yau
We clarify the recently proposed method to compute a Special K\"ahler metric
on a Calabi-Yau complex structures moduli space that uses the fact that the
moduli space is a subspace of specific Frobenius manifold. We apply this method
to computing the Special K\"ahler metric in a two-moduli non-Fermat model which
has been unknown until now
