Techniques for the Classification of Semiorthogonal Decompositions
Shinnosuke Okawa (Osaka University)
Abstract
The talk will be about the classification of semiorthogonal decompositions (SODs) of the derived category of coherent sheaves.
I will survey the known techniques and how to use them, especially to show the nonexistence of SODs for various smooth projective varieties which are minimal.
If time permits I will also mention open problems and a work in progress which have potential application to the nonexistence of phantoms on some surfaces.
