Query: Zero dielectric constant limit to the non-isentropic compressible
  Euler-Maxwell system   In this paper we investigate the zero dielectric constant limit to the
non-isentropic compressible Euler-Maxwell system. We justify this singular
limit rigorously in the framework of smooth solutions and obtain the
non-isentropic compressible magnetohydrodynamic equations as the dielectric
constant tends to zero.
