Query: Distribution of modular symbols for compact surfaces   We prove that the modular symbols appropriately normalized and ordered have
an asymptotical normal distribution for all cocompact subgroups of SL_2(R). We
introduce hyperbolic Eisenstein series in order to calculate the moments of the
modular symbols.
