Counting rational points on Hirzebruch–Kleinschmidt varieties over global function fields
Inspired by Bourqui's work on anticanonical height zeta functions on Hirzebruch surfaces, we study height zeta functions of split toric varieties with Picard rank 2 over global function fields, with respect to height functions associated with big metrized line bundles.

A comparison between obstructions to local-global principles over semiglobal fields [PDF]
We consider local-global principles for rational points on varieties, in particular torsors, over one-variable function fields over complete discretely valued fields.

Resistance Breeding Increases Winter Wheat Gross Margins–An Economic Assessment for Germany
Improved wheat varieties have ameliorated our food production. Intensive cropping systems, as in Germany, achieve very high grain yields and thus contribute greatly to global food security.

GENERALIZED EXPLICIT DESCENT AND ITS APPLICATION TO CURVES OF GENUS 3
We introduce a common generalization of essentially all known methods for explicit computation of Selmer groups, which are used to bound the ranks of abelian varieties over global fields.

Trace zero varieties in cryptography : optimal representation and index calculus [PDF]
The trace zero variety associated to an elliptic or hyperelliptic curve is an abelian variety defined over a finite field F_q. Its F_q-rational points yield a finite group, the trace zero subgroup of the degree zero Picard group of the original curve ...

Failure of the local-global principle for isotropy of quadratic forms over function fields
We prove the failure of the local-global principle, with respect to discrete valuations, for isotropy of quadratic forms over function fields of transcendence degree at least 2 over algebraically closed fields.

The $p$-adic monodromy group of abelian varieties over global function fields of characteristic $p$
We prove an analogue of the Tate isogeny conjecture and the semi-simplicity conjecture for overconvergent crystalline Dieudonné modules of abelian varieties defined over global function fields of characteristic p .

Genetically Modified Organisms (GMOs) – Part I
Introduction The phenomena and practice of improving crop and animal species seem germane to humanity across every known documented civilization. Some of these methods include cross and selective hybridization, grafting among others.
