Derivations of the Lie algebra of strictly block upper triangular matrices

Prakash Ghimire, Huajun Huang

Let $N$ be the Lie algebra of all $n \times n$ strictly block upper triangular matrices over a field $F$ relative to a given partition. In this paper, we give a…

Trace and determinant preserving maps of matrices

Huajun Huang, Chih-Neng Liu, Patricia Szokol +2

Suppose a map $ϕ$ on the set of positive definite matrices satisfies $det (A + B) = det (ϕ (A) + ϕ (B))$ . Then we have $tr (A B^{- 1}) = tr (ϕ (A) ϕ (B)^{- 1}) .$ Through this viewp…
