Abstract: In this paper, we consider singularity formation for isentropic compressible Euler equations with generalized Chaplygin gas. Firstly, through the relative equations and preliminaries, we do the characteristic decompositions of some variables, in order to establish the gradient variables and Riccati equations. Finally, we analyze the formation of singularity by giving the lower bound estimation of density.
