## Abstract We discuss constructions of string vacua with a novel Massive boson‐fermion Degeneracy Symmetry (MSDS) as candidate vacua able to describe the early non‐geometrical era of the universe.
## Abstract The existence of a new kind of __massive boson‐fermion symmetry__ is shown explicitly in the framework of the heterotic, type II and type II orientifold superstring theories. The target space‐time is two‐dimensional. Higher dimensional models are defined via large marginal deformations
## Abstract We discuss marginal deformations of string vacua with Massive boson‐fermion Degeneracy Symmetry (MSDS), in connection to the cosmological evolution of the Universe from an early non‐geometrical era. In particular, we discuss recent results on the stringy mechanism that resolves both Hag
