On the center of Kumjian-Pask algebras associated to finitely aligned k-graph

Pino, Huef, Clark, and Raeburn introduced the Kumjian-Pask algebra associated to row finite k-graph A without sources. Clark and Pangalela generalized the notion of Kumjian-Pask algebra to finitely aligned k-graph. In this paper, we survey the center of Kumjian-Pask algebras for the case finitely aligned k-graph.
