Abstract
We investigate cosmological dynamics of multiple tachyon fields with inverse square potentials. A phase-space analysis of the spatially flat FRW models shows that there exists a unique power-law cosmological scaling solution. We study the stability of the solution and find that the solution is a global attractor and a successful inflationary solution which is driven by multiple tachyon fields at lower-Planck energy densities. We briefly discuss the physical consequences of these results.
