The Arthur-Selberg trace formula is an equality between two kinds of traces; the geometric terms given by the conjugacy classes of a group and the spectral terms given by the induced representations. In general, these terms require a truncation in order to converge, which leads to an equality of truncated kernels. The formulas are difficult in general and even the case of GL(2)...(展开全部)
