Final comment to the results of Bustamante et al. on discrete Rossby/drift wave resonant and quasi-resonant triads

In this final note we demonstrate that the authors of manuscripts arXiv:1210.2036, arXiv:1309.0405 and arXiv:1309.5513 use mathematical notations and notions sometimes in the standard meaning and sometimes in a sense which differs from the standard. As this specific use is not defined beforehand, the authors' statements are self-contradictory which makes any further scientific discussion meaningless.
