Title: Non-perturbative Topological String on Compact Calabi-Yau 3-folds


Speaker: Albrecht Klemm (Bonn)


Abstract: We discuss the techniques for solving the topological string 
focussing on the recent progress in improving the high genus boundary 
conditions by considering the non-commutative resolutions of maximal 
unipotent monodromy points with Z2 torsion, the knowledge of modular 
D4-D2-D0 gauge theory indices and wall crossing formulas relating the 
latter to Donalsdon-Thomas, Pandharipande Thomas and finally Gopakunar 
Vafa invariants. The obtained high order perturbative results are used 
to confirm and extend analytic non-perturbative results based on 
resurgence techniques and in particular a transseries solution of the 
holomorphic anomaly equations.
