Weboperators representing the rotation generators (i.e. the angular momentum operators) for any quantum system, they must obey the commutation relations [J x;J y] = i~J z [J y;J z] = i~J x [J z;J x] = i~J y (5) in order for (1) to hold, i.e. in order that the rotation operations in quantum mechanics combine in the correct way. WebThe generators of Lorentz transformations are denoted by M = M and satisfy the Lorentz algebra so(1;D 1), [M ;M ˆ˙] = ˆM ˙+ ˆM ˙+ ˙M ˆ ˙M ˆ: (2) A spinor representation is a representation of the above Lorentz algebra that does not integrate to an ordinary (i.e. \single-valued") representation of the corresponding Lorentz group.
