The SIAM Activity Group on Dynamical Systems (SIAG/DS) awards the J. D. Crawford Prize every two years to one individual for recent outstanding work on a topic in nonlinear science, as evidenced by a publication in English in a peer-reviewed journal within the four calendar years preceding the award year.
The term “nonlinear science" is used in the spirit of the SIAG on Dynamical Systems conferences. Specifically, it includes dynamical systems theory and it’s applications as well as experiments, computations, and simulations.
The candidate’s research must contain significant contributions to the field of nonlinear science. One key paper must be cited as evidencing the contributions, though a body of papers may be discussed in the nomination. The qualifying key paper must have been published in English in a peer-reviewed journal published within the four calendar years preceding the award year.
For the 2021 award, the paper must have been published between the dates of January 1, 2017 - December 31, 2020.
