Artin, W. Schelter, J. Tate, and M. Van Den Bergh. This was made possible by associating certain graded modules to geometric objects, such as "point modules" to points, "line modules" to lines, etc. It is widely believed that this technique will play a major role in classifying the regular algebras of global dimension four. In this talk we will present a family of such algebras and classify all line modules over these algebras. Included in this family is the quantum universal enveloping algebra of the Lie algebra sl(2), which has many applications in mathematics and physics.
