| Outline of Final Research Achievements |
One of main themes of the study of compact Riemann surfaces is a classification problem of Riemann surfaces by the existence of meromorphic functions on them and conformal invariants. We have studied this theme. We have gotten results concerning a relation between Weierstrass points with prescribed gap sequences and involutions of Riemann surfaces, a behavior of gonality sequences, in particular, violating the slope inequality of them, and a characterization of Riemann surfaces on which the Clifford index is computed maximally.
