Tunnels under geometries (or instantons know their algebras)

Journal of High Energy Physics
In the tight binding model with multiple degenerate vacua we might treat wave function overlaps as instanton tunnelings between different wells (vacua). An amplitude for such a tunneling process might be constructed as T i → j ∼ e − S inst v j + v i − $$

Integral points on Abelian varieties

Inventiones Mathematicae, 1985
Let K be a number field, S a finite set of places of K, \(R_ S\) the ring of S-integers, and \(A| K\) an abelian variety. A conjecture of \textit{S. Lang} [''Fundamentals of diophantine geometry'' (1983; Zbl 0528.14013); p. 219] asserts, for every affine subset U of A, the finiteness of the set of points of U with coordinates in \(R_ S\).

A Chebyshev criterion for Abelian integrals

We present a criterion that provides an easy sufficient condition in order that a collection of Abelian integrals has the Chebyshev property. This condition involves the functions in the integrand of the Abelian integrals and can be checked, in many ...

On uniformizable representation for Abelian integrals

, 2012
We show how the unformizable representation for Abelian integrals of nontrivial genera arise. The technique makes use of the famous Chudnovsky's Fuchsian linear differential equations and their relation to the sixth Painleve transcendent.

Bounding the number of zeros of certain Abelian integrals

In this paper we prove a criterion that provides an easy sufficient condition in order for any nontrivial linear combination of n Abelian integrals to have at most n + k − 1 zeros counted with multiplicities.
