- We present inequalities concerning the entries of correlation matrices, density matrices, and partial isometries through the positivity of 3 × 3 matrices. We extend our discussions to the inequalities concerning the triangle triplets with metric-preserving and subadditive functions. [ABSTRACT FROM AUTHOR]
