definition of crystalline cohomology, functoriality [BO, 5.4-19], and connections [BO, 2.1-2.10].
Lusztig's theory of canonical bases reveals a remarkably rigid and positive algebraic structure on quantum groups and their modules. In symmetric types, it is known that the structure constants for multiplication in the negative part $U^-$, as well as for the action of Chevalley generators $E_i…
The "fundamental curve" of arithmetic over nonarchimedean local fields is the Fargues–Fontaine curve. You'd think the "fundamental curve" of arithmetic over global function fields is... just the associated curve over F_q. In this talk, I will instead advocate for a different "curve", in the…
