Erratum to: On the DJL conjecture for order 6

Peter J.C. Dickinson (p.j.c.dickinson***at***utwente.nl)

Abstract: In this note an erratum is provided to the article ``On the DJL conjecture for order 6'' by Naomi Shaked-Monderer, published in Operators and Matrices 11(1), 2017, 71--88. We will demonstrate and correct two errors in this article. The first error is in the statement of a proposition, which omits a certain category of extreme matrices. The second error is in the proof of a lemma. Fortunately the lemma itself is correct, and in this note we will in fact show that a stronger result holds.

Keywords: copositive matrix; exceptional matrix; minimal zeros

Category 1: Linear, Cone and Semidefinite Programming (Other )
