Representation of a 3-d City Model in Spatial Object-relational Databases
Databases GIS Modeling
2015/7/6
Three-dimensional city models become more and more important in many GIS applications. Examples are, apart from simple
visualization, city and land use planning as well as telecommunication planning ...
Not every object in the derived category of a ring is Bousfield equivalent to a module
Not every object derived category ring Bousfield equivalent module
2012/3/1
We consider the derived category of a specific non-Noetherian ring \Lambda, and show that there are objects in D(\Lambda) that are not Bousfield equivalent to any module. This answers a question posed...
Graded mutation in cluster categories coming from hereditary categories with a tilting object
Graded mutation cluster categories hereditary categories tilting object
2010/12/13
We present a graded mutation rule for quivers of clustertilted algebras. Furthermore, we give a technique to recover a clustertilting object from its graded quiver in the cluster category of cohX.
