WebJun 5, 2024 · An étale morphism of schemes $ f : X \rightarrow Y $ can be defined equivalently as a locally finitely-presentable flat morphism such that for any point $ y \in Y $ the $ k ( y) $- scheme $ f ^ { - 1 } ( y) = X \otimes _ {Y} k ( y) $ is finite and separable. An étale morphism has the lifting property for infinitesimal deformations: If $ f : X ... WebSecond definition. In a category with all finite limits and colimits, the image is defined as the equalizer (,) of the so-called cokernel pair (,,), which is the cocartesian of a morphism with itself over its domain, which will result in a pair of morphisms ,:, on which the equalizer is taken, i.e. the first of the following diagrams is cocartesian, and the second equalizing. from net income to free cash flow
