Resumen de A Mori-Nagata type theorem for seminormal Mori lattices

David E. Rush, James S. Okon, Laura J. Wallace

• It is shown that the complete integral closure of a seminormal Mori lattice is a Krull lattice. This extends a result of V. Barucci to multiplicative lattices. New results on rings are obtained by specializing to the case that the lattice is the set of homogeneous ideals of an M-graded ring where M is an abelian cancellative torsion-free monoid.
