Canonical modules of Rees algebras
Winfried Bruns, Gaetana Restuccia
We compute the canonical class of certain Rees algebras. Our formula generalizes that of Herzog and Vasconcelos. Its proof relies on the fact that the formation of the canonical mo…

Evaluation of the low-lying energy spectrum of magnetic Keplerate molecules with DMRG
Matthias Exler, Juergen Schnack
We apply the density-matrix renormalization group technique to magnetic molecules in order to evaluate the low-lying energy spectrum. In particular, we investigate the giant Kepler…
