On deep Frobenius descent and flat bundles
Holger Brenner, Almar Kaid
Let R be an integral domain of finite type over Z and let f:X --> Spec R be a smooth projective morphism of relative dimension d >= 1. We investigate, for a vector bundle E on the…
Tight closure does not commute with localization
Holger Brenner, Paul Monsky
We give an example showing that tight closure does not commute with localization.
Heat Transport in Quantum Spin Chains: Stochastic Baths vs Quantum Trajectories
Carlos Mejia-Monasterio, Hannu Wichterich
We discuss the problem of heat conduction in quantum spin chain models. To investigate this problem it is necessary to consider the finite open system connected to heat baths. We d…
Transition from diffusive to ballistic dynamics for a class of finite quantum models
Robin Steinigeweg, Heinz-Peter Breuer, Jochen Gemmer
The transport of excitation probabilities amongst weakly coupled subunits is investigated for a class of finite quantum systems. It is demonstrated that the dynamical behavior of t…
Optimized implementation of the Lanczos method for magnetic systems
J. Schnack, P. Hage, H. -J. Schmidt
Numerically exact investigations of interacting spin systems provide a major tool for an understanding of their magnetic properties. For medium size systems the approximate Lanczos…
The variety of exterior powers of linear maps
Winfried Bruns, Aldo Conca
Let be a field and and be -vector spaces of dimension and . Let be the canonical map from to . We investigate the Z…
