WebJun 5, 2024 · A flat morphism of finite type corresponds to the intuitive concept of a continuous family of varieties. A flat morphism is open and equi-dimensional (i.e. the dimensions of the fibres $ f ^ { - 1 } ( y) $ are locally constant for $ y \in Y $). For many geometric properties, the set of points $ x \in X $ at which the fibre $ f ^ { - 1 } ( f ( x ...
