AbstractConsider a quadratic polynomial $Q(\xi_{1},\dots,\xi_{n})$ of a random binary sequence $\xi_{1},\dots,\xi_{n}$. To what extent can $Q(\xi_{1},\dots,\xi_{n})$ concentrate on a single value? This is a quadratic version of the classical Littlewood-Offord problem; it was was popularised by Costello, Tao and Vu in their study of symmetric random matrices, and has since become a rich source o...
