• A note on two rational invariants for a particular 2 x 2 matrix.

      Larcombe, Peter J.; Fennessey, Eric J.; University of Derby (Palestine Polytechnic University, 2018)
      We state and prove the invariance, with respect to matrix power, of both the diagonals and anti-diagonals ratio of a special case 2×2 matrix. The proof methodology is new, contrasting with those deployed previously in establishing anti-diagonals matrix invariants.
