Bessis等人在1976年提出的猜想:当A和B是Hermite矩阵且B是半正定时,Tr(e(A-λB))是正测度的拉普拉斯变换,至今仍未得到解决。我们回顾了一些尝试对这个问题的解决方案,并提供了几个未发表的部分结果。我们还引用了一些与这个问题有关的数学问题。
The conjecture made in 1976 by Bessis, et al. that Tr(e(A-λB)) is the Laplace transform of a positive measure when A and B are Hermitean matrices and B semi positive definite is still not solved. We review some attempts made toward the solution of the question, and provide several unpublished partial results. We also quote some mathematical problems related to this question.
