On Effective log Iitaka Fibration for 3-folds and 4-folds
Gueorgui Todorov, Chenyang Xu
We prove the effectiveness of the log Iitaka fibration in Kodaira codimension two for varieties of dimension. In particular, we finish the proof of effective log Iitaka fibr…

Effective log Iitaka fibrations for surfaces and threefolds
Gueorgui Todorov
We prove an analogue of Fujino and Mori's ``bounding the denominators'' in the log canonical bundle formula (see also Prokhorov and Shokurov) for Kawamata log terminal pairs of rel…

D-branes, obstructed curves, and minimal model superpotentials
Gueorgui Todorov
In this short note we apply methods of Aspinwall-Katz to compute superpotentials of D-branes wrapped on more general obstructed rational curves in Calabi-Yau threefolds. We find an…
