Invariant theory of canonical algebras
The authors apply methods of classical invariant theory to the investigation of relative invariants of quivers with relations. In particular, they give an explicit construction of the moduli spaces (together with the quotient morphism from the corresponding representation spaces) for families of modules with a fixed dimension vector belonging to the sincere separating subcategory. Moreover using tilting theory, the results are extended to those about concealed-canonical algebras in the sense of \textit{H. Lenzing} and \textit{H. Meltzer} [Representation theory of algebras. Seventh international conference, August 22-26 (1994), Cocoyoc, Mexico, Am. Math. Soc. CMS Conf. Proc. 18, 455-473 (1996; Zbl 0863.16013)], which includes the class of tame hereditary, tame concealed and tubular algebras.
