The Simons Foundation has issued a call for proposals for their new program Simons Collaborations in Mathematics and the Physical Sciences. The aim of the program is to “stimulate progress on fundamental scientific questions of major importance in the broad area of mathematics, theoretical physics, and theoretical computer science.” An example is the Simons Collaboration on Algorithms and Geometry.
Grant sizes are up to $2.5m/year for 4 years (which can be extended to 7 years). Letters of intent are due by October 31.
