Semiorthogonal decompositions

Structure of quantum cohomology
By Hertling–Manin–Teleman we have that quantum cohomology cannot be generically semisimple, as $\mathrm{h}^{1,2}\neq 0$.
Zero section description
Fano 3-folds from homogeneous vector bundles over Grassmannians gives the following description(s):
- variety
- $\operatorname{Gr}(2,4) \times \mathbb{P}^1$
- bundle
- $\mathcal{O}(2,0) \oplus \mathcal{O}(1,1)$
See the big table for more information.
