            ``Multi-Dimensional Gas Flows, Some  Historical Perspectives.''

＜研究発表要旨＞
We present a historical perspective on the difficult subject of 
multi-dimensional gas flows. There are some key issues debated in a panel
discussion chaired by von Nuemann and attended by Heisenberg, von Karman,
Burgers and others in 1949. We will discuss this as related to the recent
developments in the shock wave theory.
