The seminar is sponsored by NYU-ECNU Institute of Mathematical Sciences at NYU Shanghai.


We present a characteristic decomposition of the Two-dimensional Euler Equations in the self-similar plane. The decomposition allows for a proof that we construct semi-hyperbolic patches of solutions, in which one family out of two nonlinear families of characteristics starts on sonic curves and ends on transonic shock waves, to the two-dimensional Euler equations. This type of solution appears in the transonic flow over an airfoil and Guderley reflection, and is common in the numerical solutions of Riemann problems.
