abstract:In algebraic geometry, an algebraic variety or scheme X is normal if it is normal at every point, meaning that the local ring at the point is an integrally closed domain. A variety over a field is normal if and only if every finite birational morphism from any variety Y to X is an isomorphism.
In a normal power scheme, after a half hour the notebook will drop to hibernate, which takes the bits in memory, puts them on the hard drive, and shuts off power to memory.
