A Zariski dense exceptional set in Manin’s Conjecture: dimension 2
نویسندگان
چکیده
Recently, Lehmann, Sengupta, and Tanimoto proposed a conjectural construction of the exceptional set in Manin’s Conjecture, which we call geometric set. We construct del Pezzo surface degree 1 whose is Zariski dense. In particular, this provides first counterexample to original version Conjecture dimension 2 characteristic 0. Assuming finiteness Tate-Shafarevich groups elliptic curves over $${\mathbb Q}$$ with j-invariant 0, show that there are infinitely many such counterexamples.

Bers Slices Are Zariski Dense
Each Bers slice is a holomorphically embedded copy of Teichmüller space within XC(S). While it follows that BY can be locally described as the common zero locus of finitely many analytic functions on XC(S), it is known that the Bers slice is not a locally algebraic set [DK]—this is used to show that W. Thurston’s skinning map is not a constant function [DK]. We prove a stronger result about the...
متن کاملA short proof of the maximum conjecture in CR dimension one
In this paper and by means of the extant results in the Tanaka theory, we present a very short proof in the specific case of CR dimension one for Beloshapka's maximum conjecture. Accordingly, we prove that each totally nondegenerate model of CR dimension one and length >= 3 has rigidity. As a result, we observe that the group of CR automorphisms associated with each of such models contains onl...
