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…

Derivations of Lie Algebras of Dominant Upper Triangular Ladder Matrices

Prakash Ghimire, Huajun Huang

We explicitly describe the Lie algebras $M_{L}$ of ladder matrices in $M_{n}$ associate with dominant upper triangular ladders $L$ , and completely characterize the derivations of these…

Direct sums of zero product determined algebras

Daniel Brice, Huajun Huang

We reformulate the definition of a zero product determined algebra in terms of tensor products and obtain necessary and sufficient conditions for an algebra to be zero product dete…
