Summing up Open String Instantons and N=1 String Amplitudes
P. Mayr
We compute the instanton expansions of the holomorphic couplings in the effective action of certain $\cx N=1$ supersymmetric four-dimensional open string vacua. These include the s…
A new kind of McKay correspondence from non-Abelian gauge theories
W. Lerche, P. Mayr, J. Walcher
The boundary chiral ring of a 2d gauged linear sigma model on a Kähler manifold classifies the topological D-brane sectors and the massless open strings between them. While it…
N=1 Heterotic string vacua from mirror symmetry
P. Mayr
We review a systematic construction of $\cx N=1$ supersymmetric heterotic string vacua using mirror symmetry. The method provides a large class of explicit solutions for stable, ho…
Low--Energy Properties of (0,2) Compactifications
P. Mayr, S. Stieberger
We investigate the low--energy properties of a Z_12 orbifold with continuous Wilson line moduli. They give rise to a (0,2) superstring compactification. Their Kaehler potentials an…
