Universal compactified Jacobians

open access: yesPortugaliae Mathematica, 2020
In this paper we describe compactifications of the universal Jacobian stack of line bundles over smooth curves obtained by considering open substacks of the moduli stack of torsion-free rank-1 simple sheaves on reduced curves of given genus.

Performance of the Atmospheric Radiative Transfer Simulator (ARTS) in the 600–1650 cm−1 Region

open access: yesRemote Sensing, 2023
The Atmospheric Radiative Transfer Simulator (ARTS) has been widely used in the radiation transfer simulation from microwave to terahertz. Due to the same physical principles, ARTS can also be used for simulations of thermal infrared (TIR).

Discrete Logarithms in Generalized Jacobians [PDF]

open access: yes, 2006
D\'ech\`ene has proposed generalized Jacobians as a source of groups for public-key cryptosystems based on the hardness of the Discrete Logarithm Problem (DLP).

The effect of satellite-derived surface soil moisture and leaf area index land data assimilation on streamflow simulations over France [PDF]

open access: yesHydrology and Earth System Sciences, 2017
This study evaluates the impact of assimilating surface soil moisture (SSM) and leaf area index (LAI) observations into a land surface model using the SAFRAN–ISBA–MODCOU (SIM) hydrological suite.

A Generic Approach to Searching for Jacobians

open access: yes, 2007
We consider the problem of finding cryptographically suitable Jacobians. By applying a probabilistic generic algorithm to compute the zeta functions of low genus curves drawn from an arbitrary family, we can search for Jacobians containing a large ...

Étude géométrique et topologique du flot géodésique sur le groupe des rotations [PDF]

open access: yesSurveys in Mathematics and its Applications, 2016
The aim of this survey paper is to investigate the algebraic complete integrability of Euler-Arnold's body description of the four dimensional rigid body, or equivalently of geodesics in SO(4) using left-invariant metrics that arise from inertia tensors,

Combinatorics of compactified universal Jacobians

open access: yes, 2019
We use orientations on stable graphs to express the combinatorial structure of the compactified universal Jacobians in degrees g-1 and g over the moduli space of stable curves, \Mgb, and construct for them graded stratifications compatible with the one ...

On a Theorem of Ziv Ran concerning Abelian Varieties Which Are Product of Jacobians

open access: yesJournal of Mathematics, 2015
We give a new proof for a theorem of Ziv Ran which generalizes some results of Matsusaka and Hoyt. These results provide criteria for an Abelian variety to be a Jacobian or a product of Jacobians. The advantage of our method is that it works in arbitrary

Jacobian pairs II

open access: yesJournal of Pure and Applied Algebra, 1991
[For part I see ibid. 72, No. 1, 39-51 (1991; Zbl 0747.13014).] This work concerns the Jacobian conjecture. Let \(k\) be an algebraically closed field of characteristic zero. A pair of polynomials \(f,g\in k[X,Y]\) is said to be a Jacobian pair if \({\partial f\over\partial X}{\partial g\over\partial Y}-{\partial f\over\partial Y}{\partial g\over ...
