It is known by a result of Gyarmati that 𝒜 + ℬ ⊂ 𝒮k ∩[1,N] implies that min(|𝒜|,|ℬ|) =Ok(logN). Here, we study how the upper bound on |ℬ| decreases, when the size of |𝒜| increases (or vice versa). In particular, if |𝒜| ≥ Ck1m m(logN)1m , then |ℬ| = Ok(m2logN), for sufficiently large N, a positive integer m and an explicit constant C > 0. For example, with m ∼ loglogN this gives: If |𝒜| ≥ CkloglogN,then |ℬ| = Ok(logN(loglogN)2).","lang":"eng"}],"file":[{"date_created":"2025-01-28T07:03:51Z","file_size":424645,"content_type":"application/pdf","file_name":"2024_QuarterlyJourMath_Elsholtz.pdf","date_updated":"2025-01-28T07:03:51Z","creator":"dernst","success":1,"access_level":"open_access","relation":"main_file","checksum":"1a06e052761d3f1e873463d6f529dd82","file_id":"18931"}],"citation":{"mla":"Elsholtz, Christian, and Lena Wurzinger. “Sumsets in the Set of Squares.” The Quarterly Journal of Mathematics, vol. 75, no. 4, Oxford University Press, 2024, pp. 1243–54, doi:10.1093/qmath/haae044.","chicago":"Elsholtz, Christian, and Lena Wurzinger. “Sumsets in the Set of Squares.” The Quarterly Journal of Mathematics.
