Abstract
En 中文
We review the construction of six-dimensional non-geometric string compactifications obtained from torus fibrations with T-duality monodromy. We take a geometric point of view where T-duality twists are identified with Dehn twists of an auxiliary surface fibered over a two dimensional base. Degenerations of this auxiliary surface define codimension-two T-duality defects. For a large class of heterotic defects, we extract the low energy physics by constructing F-theory duals that admit simple Calabi-Yau resolutions.
