1999 Grigory Isaakovich Barenblatt
... for his numerous contributions to the mathematical theory of fluid motion, solid structure, nonlinear waves, scaling and asymptotics.
2003 Martin D Kruskal
... for discovering the particle-like behaviour of solitary waves, which he named 'solitons'; for introducing the inverse scattering transform method of solving the initial-value problem for the KdV equation; and for many other contributions to applied mathematics.
2007 Peter Deuflhard
... for his contributions to algorithm-oriented numerical analysis which are fundamental and range from highly nonlinear algebraic systems through large-scale ordinary and partial differential equations to Markov chains.
