A periodic table of (generalised) Grassmannians.
$\mathbb{P}^{3}\hookrightarrow\mathbb{P}^{ 3 }$
More appropriately in this particular presentation as a quotient of the symplectic group is to consider the Grassmannian as the adjoint variety of type $\mathrm{C}_{ 2 }$, where the embedding is the second Veronese embedding into $\mathbb{P}(\mathrm{V}_{2\omega_1})=\mathbb{P}^{ 9 }$.
The small quantum cohomology is generically semisimple.
The big quantum cohomology is generically semisimple.
The eigenvalues of quantum multiplication by $\mathrm{c}_1(\mathbb{P}^{3})$ are given by:
