Holomorphic structure of superstring vacua

Classical and Quantum Gravity, 1987
String theory as it is usually presented mathematically is a theory of parametrized strings. A physical theory however should only involve non- parametrized strings. In other words the theory should be invariant under the diffeomorphism group of the circle.

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

Non-Compact Current Algebras and Heterotic Superstring Vacua

NATO ASI Series Series B: Physics, 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.
