摘要
Let A be a row-finite k-graph without sources. We investigate the relationship between the complex Kumjian-Pask algebra KPc(A) and graph algebra C*(A). We identify situations in which the Kumjian-Pask algebra is equal to the graph algebra, and the conditions in which the Kumjian-Pask algebra is finite-dimensional.
