WebMeasuring flatness consists of analyzing a surface to find how it is not perfectly flat. To do so, the first step is to acquire points on the surface that will allow you to find an envelope of two parallel planes that include all of these points. The next step is finding the smallest possible sandwich of planes, regardless of the orientation ... WebLet R be a commutative Noetherian ring with unit. A map f: M → N of R -modules is injective/surjective iff the associated map f p: M p → N p on the localization is injective/surjective for every prime ideal p of the ring R. There is an isomorphism M p = M ⊗ R R p. A sequence. is exact iff k is injective and s is surjective.
