“…Clearly, H G (x, 1) = F R G (x). As t varies between 0 and 1 within the interval (0, 1), H G (x, t) represents a smooth deformation of the system F R G , and the corresponding complex roots also vary smoothly, forming smooth paths reaching all complex zeros of F R G [3,14]. The starting points of the smooth paths, however, are not well defined, as the limit points of these paths as t → 0 are not contained in (C * ) n .…”
