Gromov-Hausdorff continuity of non-Kähler Calabi-Yau conifold transitions
Benjamin Friedman, Sébastien Picard, Caleb Suan
We study the geometry of Calabi-Yau conifold transitions. This deformation process is known to possibly connect a Kähler threefold to a non-Kähler threefold. We use balanced and…

The Strominger System and Flows by the Ricci Tensor
Sébastien Picard
This is a survey on the Strominger system and a geometric flow known as the anomaly flow. We will discuss various aspects of non-Kähler geometry on Calabi-Yau threefolds. Along th…

Calabi-Yau threefolds across quadratic singularities
Sébastien Picard
These are lecture notes on non-Kähler complex threefolds presented at the MATRIX program ``The geometry of moduli spaces in string theory''. We review some basics of Calabi-Yau ge…
