The American Mathematical Society has called for nominations for the David P. Robbins prize. The description reads:
The Robbins Prize is for a paper with the following characteristics: it shall report on novel research in algebra, combinatorics or discrete mathematics and shall have a significant experimental component; and it shall be on a topic which is broadly accessible and shall provide a simple statement of the problem and clear exposition of the work. Papers published within the six calendar years preceding the year in which the prize is awarded are eligible for consideration.
The next award of the prize will be in January 2019, and nominations close at the end of June this year. Please see the webpage for the nomination procedure.
