摘要：

Let S be a smooth complex projective surface of general type, H be a very ample divisor on S and m(S; H) be the class of (S; H). In this paper, we study a lower bound for m (S; H) - 3H(2) and we improve an inequality obtained by Lanteri. We also study (S; H) with each value of m (S; H) - 3H(2) and exhibit some examples.
