In this paper we study the existence of rational points for the family of K3 surfaces over Q given by w2=A1x16+A2x26+A3x36.When the coefficients are ordered by height, we show that the Brauer group is almost always trivial...

Let d ≥ 2. The Cheeger constant of a graph is the minimum surfaceto- volume ratio of all subsets of the vertex set with relative volume at most 1/2. There are several ways to define surface and volume here: The simplest...
