]]>That was indeed a typo: n^3/3 + O(n^3) now changed to n^/3 + O(n^2).

]]>1.Thank you very much for the post about the adjugate matrices . It is wonderful and useful and it opens the doors for additional research.

2. It would be great if you write a post ” what is Skew-Hermitian matrices and their properties ”

BEST WISHES and THANKS. ]]>

Thanks! ]]>

If you agree I would like to add the wonderful paper on the history of the SVD (you have suggested it by writing the line devoted to Beltrami and Jordan) due to G. W. Stewart: “On the Early History of the Singular Value Decomposition” (SIAM Review 35(4) (1993)). This is a very important paper in my academic life (even in my personal life).

Thank you, always, for your work.
