The linearization can be used in a variety of ways. If it happens to admit a dispersion relation, this can tell us about stability or the dispersive nature of the wave components. Linearization also WebNote the linear variation near ǫ= 0. This comes from the linear dispersion near the corners of the Brillouin zone, as discussed in the text. There are also Van Hove singularities. The discontinuity at the end points ǫ= ±3 comes from a maximum or minimum of the dispersion relation in two dimensions. (These are at k= 0).
