摘要
In 1979, Pang proved that within the class of semimonotone matrices, R-0-matrices are Q-matrices and conjectured that the converse is also true. Jeter and Pye gave a counterexample when n = 5 for the converse; namely, they gave a semimonotone matrix that is in Q but not in R-0. In this paper, we prove this conjecture for semimonotone matrices of order n <= 3 and provide a counterexample when n > 3, showing the sharpness of the result. We also provide an application of this result.
