ODE singularity for blocked linearly degenerate quasilinear hyperbolic systems

摘要

The mechanism of singularity formation is discussed for a kind of blocked quasilinear hyperbolic system with linearly degenerate characteristics, so that the ODE singularity can be shown for some kinds of complete reducible systems and, in particular, all the results in Li et al. (Math. Meth. Appl. Sci. 2008; 31:193-227) can be proved without the original assumption on the part richness.
