| Outline of Final Research Achievements |
For an l-adic sheaf on algebraic variety of positive characteristic, I defined its characteristic cycle by determining the coefficients of irreducible components of the singular support defined by Beilinson, using the Milnor formula. Using the characteristic cycle, I proved the index formula computing the Euler number. Studying the compatibility with proper push-forward, I obtained an axiomatic characterization of characteristic cycles. With Yatagawa, I proved that the characteristic cycle is independent of l.
I constructed the filtration by ramification groups for a general valuation ring under the assumption that the integer ring is relatively of complete intersection.
