Algebraic and Geometric Properties of ${\mathcal{L}}_{+}^n$-Semipositive Matrices and ${\mathcal{L}}_{+}^n$-Semipositive Cones

Aritra Narayan Hisabia, Manideepa Saha

Given a proper cone $K$ in the Euclidean space ${\mathbb{R}}^n$, a square matrix $A$ is said to be $K$-semipositive if there exists an $x\in K$ such that $Ax\in \text{int}(K)$, the t…
