The Kummer surface of A, Km(A), is the desingularization of A=, obtained by blowing up these sixteen points. This gives rise to sixteen (2. This Kummer surface is a quartic surface with sixteen nodes as its only singularities. These nodes give rise to a configuration of sixteen points and sixteen planes in \({\mathbb P}^3\) such that each plane contains exactly six points and each point belongs to exactly six planes (this is called a “(16,6.

In Hudson’s book, the Weddle surface is constructed as image of a Kummer quartic K by the rational map associated to the linear system of sextic curves passing through ten nodes ([H], pag –).

ing the particularities of a Kummer surface, one may massively optimize the point counting step. In fact, it is very well possible to compute rkPic(V F p) for primes p up to –––– Our sample consists of the resolutions of Kummer quartics with small coefficients.

For each of these surfaces, we computed the upper bounds Cited by: Eq. determines an elliptic fibration with section on the Kummer surface Kum (Jac C ′). Generically, the Weierstrass model has two singular fibers of Kodaira-type I 0 ∗ at u = 0, ∞, six singular fibers of type I 2 located over a collection of base points invariant under u.

By a kummer surface, I mean a quotient of two-dimensional complex torus by multiplication by $-1$. It is a K3 surface and known to be simply connected.

But it is not clear to me why it is simply-connected from its construction, which is a quotient of a surface with infinite fundamental group.

Is there a direct explanation or any references. Thanks. Gonzalez-Dorrego (16,6) configurations and geometry of Kummer surfaces in $\mathbf{P}^3$ Mem.

The base-ten system, which we call the “decimal” system, requires a total of ten different symbols/digits to write any number. They are, of course, 0, 1, 2, 9. WEDDLE S SURFACES Now we know that H6 serves as the moduli space for Weddle quartic surfaces, up to projective equivalence, since there exists a unique Weddle surface with 6 given points in P3 (in general position) as its nodes.

(Also, it is evident that the Weddle surface W and the genus 2 curve C have the same moduli point in H6.) 3.

Important examples of K3 surfaces with ordinary double points are furnished by the Kummer surfaces: by definition, a Kummer surface is a surface of the form = T / (z b l), where is a complex torus of complex dimension 2, so that a Kummer surface always has 16 ordinary double points^: the images of the 2-torsion subgroup by: The composition of this map with the projection off a smooth point of S 3 gives a 2: 1 rational map P 3 P 3 whose ramification locus is a Weddle surface ([19, 7]).
