In mathematics, the Grothendieck inequality states that there is a universal constant $${\displaystyle K_{G}}$$ with the following property. If Mij is an n × n (real or complex) matrix with $${\displaystyle {\Big }\sum _{i,j}M_{ij}s_{i}t_{j}{\Big }\leq 1}$$for all (real or complex) numbers si, tj of absolute value at most 1, then See more Let $${\displaystyle A=(a_{ij})}$$ be an $${\displaystyle m\times n}$$ matrix.
