More on Tachyon Cosmology in De Sitter Gravity
Harvendra Singh
We aim to study rolling tachyon cosmological solutions in de Sitter gravity. The solutions are taken to be flat FRW type and these are not time-reversal symmetric. We find that cos…

de Sitter space, (D)pp-Waves and a star-Matrix model
Harvendra Singh
We consider de Sitter spacetime solutions and the corresponding de Sitter kind of plane-wave solutions in M* theory. We attempt to write down corresponsing matrix model which is fo…
