👉 Edgeworth's theorem is a result in mathematical analysis that relates the distribution of eigenvalues of an $n \times n$ matrix to its eigenvectors. It was first published by John Edgeworth in 1936. The theorem states that if $A$ is an $n \times n$ real symmetric matrix, then $\lambda_1, \lambda_2, ..., \lambda_n$ are the eigenvalues of $A$, and $v_1,
