Query: Inflation and accelerated expansion TeVeS cosmological solutions   We find exact exponentially expanding and contracting de Sitter solutions of
the spatially homogeneous TeVeS cosmological equations of motion in the vacuum
TeVeS model and a power law accelerated expanding solution in thepresence of an
additional ideal fluid with equation of state parameter $-5/3 < \omega < -1$. A
preliminary stability analysis shows that the expanding vacuum solution is
stable, while in the ideal fluid case stability depends on model parameter
values. These solutions might provide a basis for incorporating early-time
inflation or late-time accelerated expansion in TeVeS cosmology.
