WebThe book offers a comprehensive introduction to Leavitt path algebras (LPAs) and graph C*-algebras. Highlighting their significant connection with classical K-theory—which plays an important role in mathematics and its related emerging fields—this book allows readers from diverse mathematical backgrounds to understand and appreciate these structures. WebWe are going to show that the representation dimension of a cluster-concealed algebra is 3. We compute its representation dimension by showing an explicit Auslander generator for the cluster-tilted algebra. razor mx350 mx400 kids youth training wheels
