Grothendieck inequality
WebSince the Lindenstrauss-Pelczynski paper, the Grothendieck inequality has seen many proofs; in this, it shares a common feature of most deep and beautiful results in mathematics. The proof we present is an elaboration of one presented by R. Rietz. It is very elementary. Keywords. Banach Space; Banach Lattice; WebIn this note, we will prove Grothendieck’s Inequality when H= Rm+n. The proof is mainly due to Krivine. However, we use a nice simpli cation of a key lemma in Krivine’s proof (which holds for general H), due to Alon and Naor. This will provide us with the tools to prove Alon and Naor’s theorem. Finally,
