Mori dream space
From Wikipedia, the free encyclopedia
In algebraic geometry, a Mori dream space is a projective variety whose cone of effective divisors has a well-behaved decomposition into certain convex sets called "Mori chambers".[1] Hu and Keel showed that Mori dream spaces are quotients of affine varieties by torus actions.[1] The notion is named so because it behaves nicely from the point of view of Mori's minimal model program.
