Orbits of Curves on Certain K3 Surfaces
TLDR
In this paper, the authors studied the family of algebraic K3 surfaces generated by the smooth intersection of a (1, 1) form and a (2, 2) form in the Picard number 3.Abstract:
In this paper, we study the family of algebraic K3 surfaces generated by the smooth intersection of a (1, 1) form and a (2, 2) form in \(\mathbb{P}^{2} { \times }\mathbb{P}^{2} \) defined over \(\mathbb{C}\) and with Picard number 3. We describe the group of automorphisms \(\mathcal{A} = Aut (V / {\mathbb{C}})\) on V. For an ample divisor D and an arbitrary curve C0 on V, we investigate the asymptotic behavior of the quantity \(N_{\mathcal{A}{\text{(}}C_0 {\text{)}}} (t) = \# \{ C \in \mathcal{A}{\text{(}}C_0 {\text{)}}\;{\text{:}}\;C \cdot D < t\} \). We show that the limit
$$\mathop {\lim }\limits_{t \to \infty } \frac{{\log N_{\mathcal{A}(C)} (t)}}{{\log t}} = \alpha $$
exists, does not depend on the choice of curve C or ample divisor D, and that .6515<α<.6538.read more

The Ample Cone for a K3 Surface
TL;DR: In this paper, the authors give pictorial fractal representations of the ample cone for surfaces in a certain class of K3 surfaces, which have a line parallel to one of the axes, and have Picard number four.
Dynatomic cycles for morphisms of projective varieties.
TL;DR: In this paper, the effectivity of the zero-cycles of formal periodic points, called dynatomic cycles, for morphisms of projective varieties was analyzed. But the results were not applicable to the existence of periodic points with arbitrarily large minimal periods.

Orbital Counting of Curves on Algebraic Surfaces and Sphere Packings
TL;DR: In this article, the Apollonian group associated to integral apollonian circle packings was realized as a group of automorphisms of an algebraic surface, and the asymptotic growth of degrees of elements in the orbit of a curve on a curve was studied.

Orbits of points on certain K3 surfaces
TL;DR: In this article, it was shown that for a K3 surface within a certain class of surfaces and over a number field, the orbit of a point under the group of automorphisms is either finite or its exponent of growth is exactly the Hausdorff dimension of a fractal associated to the ample cone.

Fractals and the Base Eigenvalue of the Laplacian on Certain Noncompact Surfaces
TL;DR: Bounds on the smallest or base eigenvalue for the Laplacian on the noncompact surfaces within a certain parameterized class are found and a curve is fitted to the resulting data.

A torelli theorem for algebraic surfaces of type k3
TL;DR: In this paper, it is proved that an algebraic surface of type K3 is uniquely determined by prescribing the integrals of its holomorphic differential forms with respect to a basis of cycles of the two-dimensional homology group, if the homology class of a hyperplane section is distinguished.
