David P. Robbins Prize 2022 Alin Bostan; Irina Kurkova; Kilian Raschel

Alin Bostan, Irina Kurkova, and Kilian Raschel will receive the 2022 AMS David P. Robbins Prize for their paper “A human proof of Gessel's lattice path conjecture,” published in *Transactions of the American Mathematical Society* in 2017. The paper proves highly nontrivial enumeration results on a family of lattice paths known as Gessel walks. These simple-to-describe walks have a surprisingly beautiful enumeration that withstands standard combinatorial techniques. The proof makes an inspired use of experimentation to connect the problem with a remarkable identity involving elliptic functions. Unlike previous arguments, this novel proof method avoids any reference to large-scale computation.
