Ferrimagnetic Properties of MagnetiteWe study K3 surfaces over non-closed fields and relate the notion of derived equivalence to arithmetic problems.

Thermomechanics of Ferromagnetic Bodies,Let . be the function field of a smooth projective surface . over a finite field .. In this article, following the work of Parimala and Suresh, we establish a local-global principle for the divisibility of elements in . by elements in ..

The Brauer Group Is Not a Derived Invariant,In this short note we observe that the recent examples of derived-equivalent Calabi–Yau 3-folds with diffierent fundamental groups also have diffierent Brauer groups, using a little topological K-theory.

Twisted Derived Equivalences for Affine Schemes,We show how work of Rickard and Toën completely resolves the question of when two twisted affine schemes are derived equivalent.

Universal Unramified Cohomology of Cubic Fourfolds Containing a Plane,We prove the universal triviality of the third unramified cohomology group of a very general complex cubic fourfold containing a plane. The proof uses results on the unramified cohomology of quadrics due to Kahn, Rost, and Sujatha.
