Gui-Qiang G. Chen awarded SIAG/APDE Prize

The Society for Industrial and Applied Mathematics (SIAM, USA) awards the SIAG/Analysis of Partial Differential Equations Prize (one prize every two years) to the authors of the most outstanding paper, as determined by the committee, on a topic in Partial Differential Equations published in English in a peer-reviewed journal in the four calendar years preceding the year of the award.

The committee wishes to recognize Gui-Qiang G. Chen and Mikhail Feldman for their paper, "Global Solutions of Shock Reflection by Large-Angle Wedges for Potential Flow," Annals of Mathematics, Volume 171, Issue 2 (2010), 1067-1182, "in which they proved the existence and stability of a solution for the equations of two-dimensional compressible gas dynamics, for the case of a shock reflection from a wedge. This problem, originating with work of Ernst Mach, has long defied careful mathematical analysis."
