Theoretical analysis and numerical solution to a vector equation $A x - ∥ x ∥_{1} x = b$

Yuezhi Wang, Gwi Soo Kim, Jie Meng

Theoretical and computational properties of a vector equation $A x - ∥ x ∥_{1} x = b$ are investigated, where $A$ is an invertible $M$ -matrix and $b$ is a nonnegative vector. Existence and…
