Query: Inflation in anisotropic brane universe using tachyon field   Cosmological solution to the gravitational field equations in the generalized
Randall-Sundrum model for an anisotropic brane with Bianchi I geometry and
perfect fluid as matter sources has been considered. The matter on the brane is
described by a tachyonic field. The solution admits inflationary era and at a
later epoch the anisotropy of the universe washes out. We obtain two classes of
cosmological scenario, in the first case universe evolves from singularity and
in the second case universe expands without singularity.
