摘要：In this talk, I will introduce some recent results on the study of the supersonic-sonic structures for the two-dimensional steady Euler equations. Given a space-like curve (streamline or shock wave curve) in the plane with sonic at an extreme point and supersonic on the rest, we construct a piece of sonic curve starting from the sonic extreme point and establish the existence of smooth supersonic-sonic solutions near the sonic extreme point. The regularity of the sonic curve and the uniform regularity of the solution up to the sonic curve are discussed.
