Cox rings of almost homogeneous SL2-threefolds
Antoine Vezier
We study Cox rings of normal threefolds on which SL2 acts with a dense orbit. Exploiting the method of U-invariants, we obtain combinatorial criteria for the total coordinate space…

Equivariant Cox ring
Antoine Vezier
We define the equivariant Cox ring of a normal variety with algebraic group action. We study algebraic and geometric aspects of this object and show how it is related to the ordina…
