| Outline of Final Research Achievements |
We constructed a Langlands type correspondence for p-adic coefficient theory for function fields, and as a result, I resolved Deligne's crystalline companion conjecture for curves. This was nothing but the goal of this research, and we may say that I attained it. This correspondence enables us an p-adic interpretation of cohomology theories over finite fields, and opened a new door of the theory.
The main result states that there exists a correspondence between overconvergent F-isocrystals and cuspidal automorphic representations. However, in the proof, the category of overconvergent isocrystals is too small, and we need to deal with a much wider class called the arithmetic D-modules. In the work, by completing the program of Berthelot on the construction of such theory, we were able to obtain the desired result.
