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.
