摘 要:I will discuss an analogue of Green's function on Mumford curves. The meromorphic continuation of this Green function comes from a "differential equation," and we interpret the special value at s=0 as a "volume" of the corresponding curve. Using harmonic analysis on Bruhat-Tits trees, we derive a "Kronecker limit formula" for the Green functions in question, which connects the derivative at s=0 with the Manin-Drinfeld theta functions. Following Gross' description of Néron's local height pairing on Mumford curves, the special derivative here then equals twice of the Néron's local height with sign changed.
