Negative pressure in the early universe and its effect on cosmological evolution

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

For various reasons the description of matter in terms of a negative pressure (or state of tension) may be a realistic possibility in the early universe. The effect of such a state of decompression on the evolution of the scale factor in a homogeneous and isotropic universe admitting energy-dependent bulk viscosity is briefly discussed.
