Bourgain 0 Summary WebMar 18, 2024 · Bourgain’s theorem on metric embeddings is from the paper [2]. The terminal version as stated inTheorem 1 is first stated in the paper [5] by Linial, London, and Rabinovich, and also in the paper [1] by Aumann and Rabani. The proof above is inspired from the paper [4] by Fakcharoenphol, Rao, and Talwar, which itself is
