Critical properties in long-range hopping Hamiltonians
E. Cuevas
Some properties of -dimensional disordered models with long-range random hopping amplitudes are investigated numerically at criticality. We concentrate on the correlation dimens…

Abelian exact subcategories closed under predecessors
Ibrahim Assem, Manuel Saorin
In the category of finitely generated modules over an artinian ring, we classify all the abelian exact subcategories closed under predecessors or, equivalently, all the split torsi…
