亏格为8的K3-surfaces与三次四次幂和的簇

K3-surfaces of genus 8 and varieties of sums of powers of cubic fourfolds

Atanas Iliev, Kristian Ranestad

摘要:

本文的主要结果是:6元一般三次型F的表示簇VSP(F,10)是亏格为8的K3曲面的Hilbert平方的变形所得到的光滑辛4重.发表在《纽约时报》上之后。Math.Soc.353,No.4,1455-1468(2001)中,Eyal Markman向我们指出,在定理3.17中,我们无需证明就得出结论,VSP(F,10)应该是另一个三次4-fold上的线的4-fold。我们在e-print“Addendum to K3 surfaces of genus 8 and varieties of sums of powers of cubic fourfolds”(math.AG/0611533)中纠正了这一点,在那里我们建立了一般VSP(F,10)实际上是一个新的辛4-fold,不同于三次4-fold上的线族。

英文摘要:

The main outcome of this paper is that the variety VSP(F,10) of presentations of a general cubic form F in 6 variables as a sum of 10 cubes is a smooth symplectic 4-fold obtained a deformation of the Hilbert square of a K3 surface of genus 8. After publishing it in Trans. Am. Math. Soc. 353, No.4, 1455-1468 (2001), it was noted to us by Eyal Markman that in Theorem 3.17 we conclude without proof that VSP(F,10) should be the 4-fold of lines on another cubic 4-fold. We correct this in the e-print "Addendum to K3 surfaces of genus 8 and varieties of sums of powers of cubic fourfolds" (math.AG/0611533), where we establish that the general VSP(F,10) is in fact a new symplectic 4-fold different from the family of lines on a cubic 4-fold.
