Hamilton's instability index and applications to periodic waves
Mathematics and Education in Mathematics, Tome 50 (2021), pp. 102-110
In this survey we present some results on the stability of periodic waves. The main objective is to study their stability with respect to co-periodic perturbations. In our considerations, we rely on an instability index count theories, which in turn critically depend on a detailed spectral analysis of a self-adjoint both scalar and matrix Hill operators, and in the computations of the quantities involved on the stability index.
