do i really do number theory? sometimes i have no idea how i belong to the number theory group, and not say functional analysis group? even though the only books i pretend to read are:  p-adic lie groups, nonarchimidean functional analysis and lecture notes on formal and rigid geometry? but then i realize i really don't know any functional analysis for that matter. in this talk, in very broad and crude strokes i will try to convince myself that i do number theory. come burst my bubble.
