摘要：

Let C be a smooth curve of genus g. For each positive integer r the r-gonality d (r) (C) of C is the minimal integer t such that there is with h (0)(C, L) = r + 1. Here we use nodal plane curves to construct several smooth curves C with d (2)(C)/2 < d (3)(C)/3, i.e., for which a slope inequality fails.
