Let tr be the canonical trace on the full matrix algebra $${{\cal M}_n}$$ ℳ n with unit I . We prove that if some analog of classical inequalities for the determinant and trace (or the permanent and trace) of matrices holds for a positive functional φ on $${{\cal M}_n}$$ ℳ n with φ ( I ) = n , then φ = tr. Also, we generalize Fischer’s inequality for determinants and establish a new inequality for the trace of the matrix exponential.

行列式的不等式和迹线的表征

令 tr 是全矩阵代数 $${{\cal M}_n}$$ ℳ n 上的规范迹线,单位为 I 。我们证明,如果矩阵的行列式和迹(或永久和迹)的经典不等式的一些模拟对于 $${{\cal M}_n}$$ ℳ n 上的正泛函 φ 成立,其中 φ ( I ) = n ,则 φ = tr。此外,我们对行列式的 Fischer 不等式进行了推广,并为矩阵指数的迹建立了一个新的不等式。
