Description
We study the BPS index (a kind of generalized partition function) for
the classic four-dimensional rank-one N=2 superconformal field
theories H_0, H_1, H_2, E_6, E_7, E_8. We consider compactifications
of the 6d E-string theory on T^2 in which these theories arise as low
energy limits. Using this realization we clarify the general structure
of the BPS index. The index is characterized by two exponents and a
sequence of invariants. We determine the exponents and the first few
invariants.
