Hardy, 0. H. und J. E. Littlewood, Some problems of ´Partitio Numerorum´ (VT): Further Researches m Waring´s Problem
For a cocompact group of we fix a real non-zero harmonic -form . We study the asymptotics of the hyperbolic lattice-counting problem for under restrictions imposed by the modular symbols . We prove that the normalized values of the modular symbols, when ordered according to this counting, have a Gaussian distribution.
