On Surfaces with a Canonical Pencil
We classify the minimal surfaces of general type with K ≤ 4χ− 8 whose canonical map is composed with a pencil, up to a bounded family. More precisely we prove that there is exactly one irreducible family for each value of χ ≫ 0, 4χ− 10 ≤ K ≤ 4χ− 8. All these surfaces are complete intersections in a toric 4−fold. They can also be obtained as bidouble covers of Hirzebruch surfaces.
متن کاملOn Rationality of Nonsingular Threefolds with a Pencil of Del Pezzo Surfaces of Degree 4
We prove a criterion of nonsingularity of a complete intersection of two fiberwise quadrics in P P 1 (O(d 1) ⊕. .. ⊕ O(d 5)). As a corollary we derive the following addition to the Alexeev theorem on rationality of standard Del Pezzo fibrations of degree 4 over P 1 : we prove that any fibration of this kind with the topological Euler characteristic χ(X) = −4 is rational.
متن کاملThe Canonical Height on K 3 Surfaces
Let S be a surface in P2 × P2 given by the intersection of a (1,1)form and a (2,2)-form. Then S is a K3 surface with two noncommuting involutions σx and σy . In 1991 the second author constructed two height functions ĥ+ and ĥ− which behave canonically with respect to σx and σy , and in 1993 together with the first author showed in general how to decompose such canonical heights into a sum of lo...

متن کاملCanonical Surfaces in P
— In [Böh] a structure theorem for Gorenstein algebras in codimension 2 was obtained. In Section 1 of this article we give a geometric application and prove a structure theorem for good birational canonical projections of regular surfaces of general type with pg = 5 to P4 (Theorem 1.6). In Section 2 we show how this can be used to analyze the moduli space of canonical surfaces with q = 0, pg = ...
