Abstract: The category of regular representations for a tame hereditary algebra decomposes into tubes, say with indexing set X. Using the preprojective algebra we can endow X with the structure of a non-commutative curve, as shown by Baer, Geigle and Lenzing. We will discuss their construction and describe the connections between the geometry of the non-commutative curve, the ring-theoretic properties of the preprojective algebra, and the category of regular modules.
