On metric approximate subgroups
Let G𝐺 be a group with a metric invariant under left and right translations, and let Dr𝔻𝑟 be the ball of radius r𝑟 around the identity. A (k,r)(𝑘,𝑟)-metric approximate subgroup is a symmetric subset X𝑋 of G𝐺 such that the pairwise product set XX𝑋𝑋 is covered by at most k𝑘 translates of XDr𝑋𝔻𝑟. This...
