Abstract:

In this paper, by introducing a new idea, we prove the uniqueness of weak solution of pressureless gases with the large initial data. In particular, our uniqueness theorem is obtained in the same functional space as the existence theorem.

Key words: Pressureless gases, generalized potential, generalized characteristic, measurevalue solution
