Abstract: As it turned out a while ago there is an easy, yet extremely powerful construction of Jacobi forms, which has also consequences for the theory of elliptic modular forms. Despite its simpleness this construction is related to various interesting problems concerning trigonometric polynomials, the arithmetic theory of lattices and the theory of Kac-Moody algebras. We shall report about this construction, the mentioned connections to other theories and recent results. Many of these results would not have been discovered without a lot of preceding computational experimentation. We shall also try to report about this aspect. The talk is partly based on joint work with Valery Gritsenko and Don Zagier.
