WebMar 3, 2016 · For the positive statement, let d ≤ e be the smallest and largest dimensions occurring among the components. Slice all fibers with the same general codimension d plane, to get X ′. Now the special fiber has some isolated points, that were in its d -component. If e > d, then the general fiber is still irreducible by Bertini, so connected. Web33.19 Dimension of fibres. 33.19. Dimension of fibres. We have already seen that dimension of fibres of finite type morphisms typically jump up. In this section we discuss the phenomenon that in codimension this does not happen. More generally, we discuss how much the dimension of a fibre can jump. Here is a list of related results:

WebIn view of my above comment about geometric fibers, any search for a counterexample will necessarily have to involve a special fiber that is reduced yet not geometrically reduced. In other words, any counterexample will have to involve an imperfect residue field at the special point in the base. WebThe generic fiber, equally, is the fiber above the generic point. Geometry of degeneration is largely then about the passage from generic to special fibers, or in other words how specialization of parameters affects matters.

My intuition suggests that the fiber over the generic point $\eta \in \mathbb{A}^1$ should have something to do with this "generic" fiber over a nonzero point. Isn't it right?

WebMore generally, if Xis a topological space and x ∈Xis a point of Xsuch that {x} = X, then x is called a generic point of X(see p. 74 in Hartshorne [10]). 3.2. Remarks. 1.

Webweakly special subvarieties of Ag; here we consider Ag as a Shimura variety. For any irreducible closed subvariety Y of Ag, we use YbiZar to denote the minimal bi-algebraic subvariety containing Y. Lemma 3.1. Let Y ⊆Ag be an irreducible closed subvariety that is bi-algebraic and let η∈π(Y) be the generic point.

The ﬁrst part is devoted to some deﬁnitions and facts about elliptic curves, as a special case. There, we wish to explain the criterion of Neron-Ogg-Shafarevich on reduction of an elliptic curve. Then in the second part, by introducing models of a curve, we get back to the notion
