Pesenti–Szpiro inequality for optimal elliptic curves
We study Pesenti–Szpiro inequality in the case of elliptic curves over Fq(t) which occur as subvarieties of Jacobian varieties of Drinfeld modular curves. In general, we obtain an upperbound on the degrees of minimal discriminants of such elliptic curves in terms of the degrees of their conductors and q. In the special case when the level is prime, we bound the degrees of discriminants only in ...
متن کاملPolarizations on abelian subvarieties of principally polarized abelian varieties with dihedral group actions
For any n ≥ 2 we study the group algebra decomposition of an ([ 2 ] + 1)dimensional family of principally polarized abelian varieties of dimension n with an action of the dihedral group of order 2n. For any odd prime p, n = p and n = 2p we compute the induced polarization on the isotypical components of these varieties and some other distinguished subvarieties. In the case of n = p the family c...
متن کاملThe André-Oort conjecture for products of Drinfeld modular curves
Let Z = X1×· · ·×Xn be a product of Drinfeld modular curves. We characterize those algebraic subvarieties X ⊂ Z containing a Zariski-dense set of CM points, i.e. points corresponding to n-tuples of Drinfeld modules with complex multiplication (and suitable level structure). This is a characteristic p analogue of a special case of the André-Oort conjecture.

The André-Oort conjecture for Shimura varieties over C states that any subvariety X of a Shimura variety S/C containing a Zariski-dense set of special points must be of Hodge type. For an up-to-date overview of this topic, and of known results, see Rutger Noot’s Bourbaki talk [18]. The most significant result so far is due to Bas Edixhoven and Andrei Yafaev [9], who prove that any subcurve X ⊂ ...
متن کاملAbelian solitons
We describe a new algebraically completely integrable system, whose integral manifolds are co-elliptic subvarieties of Jacobian varieties. This is a multi-periodic extension of the Krichever-Treibich-Verdier system, which consists of elliptic solitons. The goal of this work is to generalize the theory of elliptic solitons, which was developed by A. Treibich and J.-L. Verdier based on earlier wo...
