Some remarks on matrix stability with application to Turing instability
AbstractAn example of a 4×4 matrix is given that provides a counterexample to a result on Turing (diffusion-driven) instability and also answers negatively a conjecture on strong stability. Such instability is shown to arise from nonreal eigenvalues. The relevance and the connection of our example to classes of matrix stability known in the literature are discussed
