Integral Points on Punctured Abelian Surfaces [PDF]

open access: yes, 2002
We study the density of integral points on punctured abelian surfaces. Linear growth rates are observed experimentally.

Calabi–Yau threefolds and moduli of abelian surfaces I [PDF]

open access: yes, 2001
We describe birational models and decide the rationality/unirationality of moduli spaces $\cal A$d (and $\cal A$levd) of (1, d)-polarized Abelian surfaces (with canonical level structure, respectively) for small values of d.

Generic dijet soft functions at two-loop order: uncorrelated emissions

open access: yesJournal of High Energy Physics, 2020
We extend our algorithm for automating the calculation of two-loop dijet soft functions to observables that do not obey the non-Abelian exponentiation theorem, i.e.

Pseudo-abelian integrals: Unfolding generic exponential case [PDF]

open access: yes, 2009
We consider functions of the form H0=P1a1⋯PkakeR/Q, with Pi, R, and Q∈R[x,y], which are (generalized Darboux) first integrals of the polynomial system MdlogH0=0.

The Return Map for a Planar Vector Field with Nilpotent Linear Part: A Direct and Explicit Derivation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
Using a direct approach the return map near a focus of a planar vector field with nilpotent linear part is found as a convergent power series which is a perturbation of the identity and whose terms can be calculated iteratively.

New form of the NSVZ relation at the two-loop level

open access: yesPhysics Letters B, 2018
Recently the exact NSVZ β-function was rewritten in the form of a relation between the β-function and the anomalous dimensions of the quantum gauge superfield, of the Faddeev–Popov ghosts, and of the matter superfields.

3 definitions of BF theory on homology 3-spheres

open access: yesJournal of High Energy Physics, 2023
3-dimensional BF theory with gauge group G (= Chern-Simons theory with non-compact gauge group TG) is a deceptively simple yet subtle topological gauge theory.

A Chebyshev criterion for Abelian integrals [PDF]

open access: yes, 2011
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 ...
