SUMMARY:Matthew Kwan\, Exponential anticoncentration of the permanent
DESCRIPTION:Let A be a random n×n matrix with independent entries\, and suppose that the entries are “uniformly anticoncentrated” (for example\, A could be a uniformly random n×n matrix with ±1 entries). We prove that the permanent of A is exponentially anticoncentrated\, significantly improving previous bounds of Tao and Vu. Our proof also works for the determinant\, giving an alternative proof of a classical theorem of Kahn\, Komlós and Szemerédi. Joint work with Zach Hunter and Lisa Sauermann.
