Resumen:

We present a cosmological landscape where the classical closed string tachyon field plays an important role in the framework of a critical bosonic compactification. Our cosmological solutions for a universe with constant curvature describes an finite inflationary stage which expands till a maximum value before undergoes a big crunch as the tachyon reaches the minimum of its potential. © 2015, World Scientific.
