The definition is a little awkward in English to me. I would write

        This is defined as the signature of the symmetric matrix

        .. MATH::

             V + V^{t},

        where `V` is the :meth:`Seifert matrix <seifert_matrix>`.

Another option would be a separate initial sentence Let `V` be the :meth:`Seifert matrix <seifert_matrix>`.

Otherwise LGTM.

Many thanks for still taking the time to review my many tickets, and sorry for the rough English.

Thank you. No problem. A lot of these tickets are fairly easy to review (with the patchbot). For those sentences, I was thinking it might have been a natural construct in French :).
