    Apparent Moral:There is topologicalpersistence in particle properties

    for the surfaces.

    To what extent do the surfacesrepresent the elementary particles?

    To what extent does the framed braidand/or its algebraic representation

    represent theelementary particles?

    Algebra Appendix

    A permutation matrix P is a matrix whose columns are a permutation of the rows of the identity matrix. Such a matrix acts as a permutation on thestandard basis (column vectors that have a single unit entry). We shall refer to

    P as a permutation. If D is a diagonal matrix and P is a permutation matrix,thenP D = D P P

    where D P denotes the result of permuting the elements of D along the diagonalaccording to the permutation P.
