Abstract:
We study heterotic/type I
duality in $d=8,9$ uncompactified dimensions.
We consider
the special (``BPS saturated'') ${\cal F}^4$ and
${\cal R}^4$ terms in the
effective one-loop heterotic action, which are expected to be
non-perturbatively exact. Under the standard
duality map these translate to tree-level, perturbative and
non-perturbative contributions on the type I side. We check
agreement with the one-loop open string calculation, and discuss
the higher-order perturbative
contributions, which arise because of the
mild non-holomorphicities of the heterotic elliptic genus.
We put the heterotic world-sheet instanton corrections in a form
that can be motivated as arising from a D-brane instanton
calculation on the type I side.
