# Delbert Ray Fulkerson Prize

The Fulkerson Prize is awarded for outstanding papers in the area of discrete mathematics. The term "discrete mathematics" is interpreted broadly and is intended to include graph theory, networks, mathematical programming, applied combinatorics, applications of discrete mathematics to computer science, and related subjects.

**Prize Details**

This award is sponsored jointly by the Mathematical Optimization Society (formerly the Mathematical Programming Society) and the American Mathematical Society (AMS). Up to three awards of US$1500 are presented at each (triennial) International Symposium of the MPS. Eligible papers should represent the final publication of the main result(s) and should have been published in a recognized journal or in a comparable, well-refereed volume intended to publish final publications only, during the six calendar years preceding the year of the Symposium. The prizes will be given for single papers, not series of papers or books, and in the event of joint authorship the prize will be divided.

**Most Recent Prize: 2015**

The 2015 Fulkerson Prize was awarded to Francisco Santos, for "A Counterexample to the Hirsch Conjecture", *Annals of Mathematics*, 2012. "For almost 50 years, many well-known mathematicians have tried unsuccessfully to settle the conjecture, until a counterexample was cleverly constructed by Francisco Santos. Santos constructs a 43-dimensional polytope with 86 facets having diameter at least 44. So it lives in a space where intuition has left most of us. To construct the counterexample, Santos combines ideas and techniques stemming from various disciplines of mathematics. Although he gives a negative answer to a highly visible and more than half a century old conjecture, his methods substantially influence today's mathematics. This is witnessed by the large number of follow-up papers that build on this award-winning paper and carry his techniques further on."

**About this Prize**

Originally, the prizes were paid out of a memorial fund administered by the AMS that was established by friends of the late Delbert Ray Fulkerson (1924-1976) to encourage mathematical excellence in the fields of research exemplified by his work. The prizes are now funded by an endowment administered by the Mathematical Optimization Society.
