A Harder-narasimhan Theory for Kisin Modules
نویسنده
چکیده
We develop a Harder-Narasimhan theory for Kisin modules generalizing a similar theory for finite flat group schemes due to Fargues [Far10]. We prove the tensor product theorem, i.e., that the tensor product of semistable objects is again semi-stable. We then apply the tensor product theorem to the study of Kisin varieties for arbitrary connected reductive groups.

On F - Crystalline Representations
We extend the theory of Kisin modules and crystalline representations to allow more general coefficient fields and lifts of Frobenius. In particular, for a finite and totally ramified extension F/Qp, and an arbitrary finite extension K/F , we construct a general class of infinite and totally wildly ramified extensions K∞/K so that the functor V 7→ V |GK∞ is fully-faithfull on the category of F ...

متن کاملThe Harder-Narasimhan system in quantum groups and cohomology of quiver moduli
Methods of Harder and Narasimhan from the theory of moduli of vector bundles are applied to moduli of quiver representations. Using the Hall algebra approach to quantum groups, an analog of the Harder-Narasimhan recursion is constructed inside the quantized enveloping algebra of a KacMoody algebra. This leads to a canonical orthogonal system, the HN system, in this algebra. Using a resolution o...
متن کاملTHE CORRESPONDENCE BETWEEN BARSOTTI-TATE GROUPS AND KISIN MODULES WHEN p = 2
Let K be a finite extension over Q2 and OK the ring of integers. We prove the equivalence of categories between the category of Kisin modules of height 1 and the category of Barsotti-Tate groups over OK .
متن کاملHarder-Narasimhan categories
We propose a generalization of Quillen’s exact category — arithmetic exact category and we discuss conditions on such categories under which one can establish the notion of Harder-Narasimhan filtrations and Harder-Narsimhan polygons. Furthermore, we show the functoriality of Harder-Narasimhan filtrations (indexed by R), which can not be stated in the classical setting of Harder and Narasimhan’s...
