On distribution of the integral $2\times2$ matrices

E. P. Golubeva


Abstract: The integral solutions of equation $ad-bc=n$ in terms of spectral data of the automorphic Laplacian are investigated. Well-known results are improved in some cases. It is observed that general case can be treated by the same method.
