BPS-states and automorphic representations of exceptional groups

Automorphic forms on exceptional Lie groups appear naturally in string theory compactifications. They manifest themselves as couplings in higher derivative corrections and in terms of generating functions of BPS-states. I will explain how to treat automorphic forms in the modern theory of automorphic representations, which can be directly connected to BPS-states in string theory. Various recent results, conjectures and open problems are outlined.
