Surface braidsare defined by Rudolph [13], [14] and Viro [18], correspondin g to oriented surface-links. Viro [18] and Kamada [10] proved th e Alexander’s theorem and Markov’s theorem for the oriented surface-links and surfac e braids. In this paper, we will give the lower bound ofw-index for non-ribbon oriented surface-links and determine values for some examples. We review some definitions and notations for surface braids. Refer to [6] for more details. Let 2 1, 2 2 be 2-disks, and : 2 1 × 2 2 → 2 ( = 1, 2) be the projection map to the -th factor. Let be a set of interior points of 2 1.
