Symmetries on the moduli space of (2,2) superstring vacua
Nuclear Physics B, 1991 Abstract Symmetries of the space of (2,2) string vacua for c = 3, 6, 9 are discussed in the context of orbifoldized Landau-Ginzburg theories. A general method for finding the maximal symmetry groups on the moduli space of untwisted marginal operators is presented, by studying deformations of superpotentials.

Non-Compact Current Algebras and Heterotic Superstring Vacua
, 1990 It has been shown that a four dimensional finite and consistent superstring theory [1] can be constructed by combining any 2-dimensional superconformai field theory with a central charge c=9 with a superstring propagating in flat 4-dimensional Minkowski space-time.

Holomorphic structure of superstring vacua [PDF]
Classical and Quantum Gravity, 1987 The authors explicitly construct the vacua of the bosonic and fermionic string and corresponding ghost systems as holomorphic vector bundles over Diff(S1)/S1. They give a simple method for calculating curvatures of these bundles. Possible application to string field theory is briefly discussed.

Spontaneous splitting and internal isometries of superstring vacua
Journal of Mathematical Physics, 1987 Superstring vacua are normally presumed to be of the form M×K, where dim(M)=4, dim(K)=6, and where × denotes the global Riemannian product. Since, however, one would ultimately wish to understand the external/internal distinction in terms of some dynamical mechanism (‘‘spontaneous splitting’’) involving vacuum expectation values of local fields, it may

(2, 2) VACUA OF THE HETEROTIC SUPERSTRING COMPACTIFIED ON SU(2)3 GROUPFOLDS
International Journal of Modern Physics A, 1991 In this paper we classify the (2, 2) superstring vacua corresponding to non-linear σ-models on SU (2)3 groupfolds fermionized by 18 + 18 Majorana fermions. For the subclass of the completely bosonizable vacua, the generation number ½X is a multiple of 12 and the number of tangent-bundle deformations End(T) is a multiple of 4.

Superstring cosmology for N_4 = 1 -> 0 superstring vacua
2010We study the cosmology of perturbative heterotic superstring theory during the radiation-like era for semi-realistic backgrounds with initial $\N=1$ supersymmetry. This analysis is valid for times after the Hagedorn era (or alternatively inflation era) but before the electroweak symmetry breaking transition.
