摘要
Modeling the potential by an inverse square law in terms of the tachyon field [V(T)=betaT(-2)] we find an exact solution for a spatially flat isotropic universe. We show that for beta>2root3/3 the model undergoes power-law inflation. A way to construct other exact solutions is specified and exemplified.
