 ial-Conference/1/">K-stability from a non-Archimedean perspective.</a>\nby
  Mattias Jonsson (University of Michigan\, USA) as part of Tropical Geomet
 ry\, Berkovich Spaces\, Arithmetic D-Modules and p-adic Local Systems\n\n\
 nAbstract\nK-stability was introduced in complex differential geometry as 
 a conjectural criterion (the YTD conjecture) for the existence of special 
 Kähler metrics\, such as Kähler-Einstein metrics\, or constant scalar cu
 rvature Kähler metrics. There has been a great deal of recent activity ar
 ound K-stability: the YTD conjecture is solved in many cases\, a nice pict
 ure for K-stable Fano varieties has emerged\, and there is an increased un
 derstanding of the notion of K-stability itself. In my talk\, I will expla
 in how K-stability can be viewed through the lens of non-Archimedean geome
 try. This is based on joint work with Berman\, Blum\, Boucksom\, and Hisam
 oto.\n

 ms\n\n\nAbstract\nTropical differential equations were introduced in 2015 
 by Dima\nGrigoriev\, whose interest was in the computational complexity of
 \nfinding the supports of power series solutions of systems of linear\nODE
 s.  The next year\, Fuensanta Aroca\, Cristhian Garay and Zeinab\nToghani 
 proved a Fundamental Theorem showing that every tropical\nsolution of a di
 fferential ideal lifts to a solution over a field.\nI'll present this theo
 ry and some of the developments Zeinab\, I and\nothers have achieved since
 \, such as extensions to PDEs and connections\nto Groebner theory.\n

  variety without differential form\, every local system has finite monodro
 my (Brunebarbe-Klingler-Totaro). In work in progress with Michael Groechen
 ig\, we develop a positive characteristic analog. We¢ll discuss the rank 
 2 case and how ideally it relates to isocrystals.\n

 oefficients.</a>\nby Christine Huyghe (Université Strasbourg\, France) as
  part of Tropical Geometry\, Berkovich Spaces\, Arithmetic D-Modules and p
 -adic Local Systems\n\n\nAbstract\nThe ring of differential operators with
  overconvergent coefficients plays a central role in Berthelot's theory of
  arithmetic D-modules over a formal scheme\, as well as in Caro's theory o
 f overholonomic modules. It is constructed over the complement of a diviso
 r of some smooth formal scheme. We would like to explain how to do such a 
 construction in the case where we have a non necessary smooth divisorial c
 ompactification of some smooth formal scheme.\n

 s p-adic properties of period functions\, that were discovered by Bernard 
 Dwork in his work on rationality of zeta functions. I will demonstrate the
 ir generalization and explain a cohomological proof. Our proof uses an exp
 licit Dwork-style construction of Cartier operation on differential forms 
 on toric hypersurfaces. This is joint work with Frits Beukers.\n

 >\nby Jeffrey Giansiracusa (Swansea University\, UK) as part of Tropical G
 eometry\, Berkovich Spaces\, Arithmetic D-Modules and p-adic Local Systems
 \n\n\nAbstract\nA few years ago Grigoriev introduced the concept of tropic
 alization of differential equations\, and then Aroca et al. proved that th
 ere is an analogue of the fundamental theorem of tropical geometry\, where
  any solution at the tropical level can be lifted to a classical solution.
  Unfortunately\, this theory is limited in its applicability\, since it on
 ly works with trivial valuations. In this talk I will describe the work of
  Stefano Mereta to build a general framework for tropical differential equ
 ations over non-trivially valued rings\, thus allowing potential applicati
 ons to p-adic differential equations. This involves some interesting twist
 s\, such as a tropical variant of the Leibniz rule. We support our theory 
 with a differential analogue of Payne's inverse limit theorem.\n
