Abstract:

This paper studies the formation of singularities in smooth solutions to three-dimensional (3D) spherically symmetric relativistic Euler matrixs with a Chaplygin gas matrix of state. We give a sufficient condition on the initial data to obtain that the mass-energy density itself of the classical solutions to the Cauchy problem blows up in finite time.

Key words: Relativistic Euler matrixs, Chaplygin gas, Singularities formation, Characteristic decomposition
