On some sign patterns of algebraically positive matrices
On some sign patterns of algebraically positive matrices is a scholarly work, published in 2019 in ''Linear Algebra and its Applications''. The main subjects of the publication include path, sign, algebraic number, pure mathematics, matrix, Lie algebra, tree, numerical linear algebra, combinatorics, and mathematics. The authors give a new characterization of algebraically positive matrices, and characterize all tree sign pattern matrices that allow algebraic positivity, and all star and path sign pattern matrices that require algebraic positivity.
