We construct time dependent BPS pp-wave brane solutions in the context ofM-theory and type II supergravity. It is found that N-brane solutions weconsidered satisfy the crossing rule as S-brane solutions but 1/8 supersymmetryremains. By applying them to the cosmological setting, inflationary solutionsare obtained. During this inflation, the size of the extradimensions becomessmaller than our four-dimensional spacetime dynamically. We also discuss themechanism for terminating this inflation and recovering the hot big-banguniverse.Comment: 10 page
