Effectivity of Brauer-Manin obstructions
Andrew Kresch, Yuri Tschinkel
We study Brauer-Manin obstructions to the Hasse principle and to weak approximation with special regard to effectivity questions.
Low-dimensional Singularities with Free Divisors as Discriminants
Ragnar-Olaf Buchweitz, Wolfgang Ebeling, Hans-Christian Graf v. Bothmer
We present versal complex analytic families, over a smooth base and of fibre dimension zero, one, or two, where the discriminant constitutes a free divisor. These families include…
Asymptotic generators of fermionic charges and boundary conditions preserving supersymmetry
Stefan Hollands, Donald Marolf
We use a covariant phase space formalism to give a general prescription for defining Hamiltonian generators of bosonic and fermionic symmetries in diffeomorphism invariant theories…
Phase lapses in transmission through interacting two-level quantum dots
C. Karrasch, T. Hecht, A. Weichselbaum +3
We investigate the appearance of pi lapses in the transmission phase theta of a two-level quantum dot with Coulomb interaction U. Using the numerical and functional renormalization…
Lie Group Structures on Symmetry Groups of Principal Bundles
Christoph Wockel
In this paper we describe how one can obtain Lie group structures on the group of (vertical) bundle automorphisms for a locally convex principal bundle P over the compact manifold…
Universal properties of highly frustrated quantum magnets in strong magnetic fields
Oleg Derzhko, Johannes Richter, Andreas Honecker +1
The purpose of the present paper is two-fold. On the one hand, we review some recent studies on the low-temperature strong-field thermodynamic properties of frustrated quantum spin…
