    The Idea-section of this entry was no good, besides being extremely brief. I have now written a few paragraphs (here). Still much room to improve on this, but it should be a start.

    I have renamed the entry from “topological state of matter” to “topological phase of matter”. The latter is the established terminology, and the former doesn’t really make sense.

    In that introductory paragraph

    … if external adiabatic deformations of the system that are gentle enough not to excite modes beyond energy >Δ above the ground state leave the properties of the system invariant if the deformations are small…

    the final “if the deformations are small” is a repetition? The whole paragraph being a single sentence it’s hard to parse.

    Right, thanks for pushing me. I have now adjusted and then I have expanded the idea-section a fair bit more (still here)

    added also a paragraph (now here) making the relation to TQFT more explicit
