Bruce Reznick 66 fest: A mensch of Combinatorial-Algebraic Mathematics

[] [] []

On July 8, 2019, the day before the start of the 2019 SIAM conference on Applied Algebraic Geometry, we will hold a one-day symposium to celebrate the work and career of our esteemed colleague Bruce Reznick.

Bruce is well-known to many people for his work in the general area of combinatorial-algebraic-analytic investigations of polynomials and numbers. In particular, Bruce is well-known for his seminal contributions to the study of sums of squares and positivity of polynomials. Bruce is also known as a caring teacher and mentor. He has been a generous and kind supporter and mentor of young researchers for many years.

    The symposium will take place at the University of Bern, the same venue as the SIAM conference. More precisely:
