RT Journal Article T1 Orthogonality for (0, −1) tropical normal matrices A1 Bakhadly, Bakhad A1 Guterman, Alexander A1 Puente Muñoz, María Jesús De La AB We study pairs of mutually orthogonal normal matrices with respect to tropical multiplication. Minimal orthogonal pairs are characterized. The diameter and girth of three graphs arising from the orthogonalityequivalence relation are computed.
