On the period-index problem in light of the section conjecture

Jakob Stix

Period and index of a curve over a -adic local field such that the fundamental group admits a splitting are shown to be powers of . As a consequence, exa…

Remarks on derived equivalences of Ricci-flat manifolds

Daniel Huybrechts, Marc Nieper-Wisskirchen

We present results indicating that the decomposition of a Ricci-flat manifold in its irreducible factors is reflected by the derived category of coherent sheaves. More precisely, w…

On the Hodge-Newton filtration for p-divisible O-modules

Elena Mantovan, Eva Viehmann

The notions Hodge-Newton decomposition and Hodge-Newton filtration for F-crystals are due to Katz and generalize Messing's result on the existence of the local-étale filtration for…

Deligne-Lusztig varieties and period domains over finite fields

S. Orlik, M. Rapoport

We prove that the Drinfeld halfspace is essentially the only Deligne-Lusztig variety which is at the same time a period domain over a finite field. This is done by comparing a coho…

Local Models in the ramified case. III. Unitary groups

G. Pappas, M. Rapoport

We continue our study of the reduction of PEL Shimura varieties with parahoric level structure at primes p at which the group that defines the Shimura variety ramifies. We describe…

-objects and autoequivalences of derived categories

D. Huybrechts, R. P. Thomas

We describe new autoequivalences of derived categories of coherent sheaves arising from what we call -objects of the category. Standard examples arise from holomorphic…
