Abstract

The automorphic forms in rather misterious way appear in different branches of mathematics from number theory to mathematical physics. At the other hand, the technique of this theory includes methods from various parts of mathematics like complex analysis, topology, differential geometry, Lie groups theory, number theory. Nevertheless, the main notions and concepts of this deep theory can be illustrated without use of comlicated tools.
