Statement of Interest:


  Various aspects of topological strings on Calabi-Yau
manifolds such as the computation of Gopakumar-Vafa 
invariants and non-perturbative contributions to the N=1
superpotential in 4D gauge theories. A different aspect is
the interplay between geometry and conformal field theory 
descriptions of these theories and in particular their D-
branes, using e.g. matrix factorizations. This aspect leads 
beyond the topological limit and allows the study the
massive modes using chiral CFTs on Calabi-Yau manifolds.
The relevant framework is the so-called chiral de Rham 
complex which is related to heterotic (0,2) 
compactifications.
