| 抄録: | This is a research announcement about a study of characteristic cycle of a rank 1 sheaf on a surface on which I am writing a paper. In this announcement, we construct a canonical lifting of Kato's logarithmic characteristic cycle on the cotangent bundle of the surface. As a corollary, an index formula computing the Euler characteristic of the sheaf is yielded by the canonical lifting. |
