{wiki=Deviation_of_a_local_ring}
The concept of deviation in the context of local rings can refer to different things depending on the specific mathematical setting. However, in algebraic geometry and commutative algebra, the term "deviation" is often related to the concept of "dualizing complexes", "canonical modules", or even to certain homological dimensions relative to local rings.
