Naoki Tsuge, Spherically Symmetric Flow of the Compressible Euler Equations


Abstarct
 We study the Euler equations of compressible isentropic gas dynamics with 
spherical symmetry. Due to the presence of the singularity at the
origin, little is also known in the case including the origin. In this
paper, we prove the existence of local solutions for the case
including the origin.
