Title: Quasi-neutral limit of the flow of a chemically reacting gaseous mixture for ionic dynamics Author: Young-Sam Kwon (Dong-A Univ., Busan 604-714, Korea) Abstract: In this article we consider the quasi-neutral limit of the compressible flow of a chemically reacting gaseous mixture in the periodic domain $\mathbb{T}^3$ with the well-prepared initial data. We prove that the weak solution of the compressible flow of a chemically reacting gaseous mixture converges to the strong solution of the compressible flow of reacting gaseous mixture as long as the latter exists.
