The Kumjian–Pask algebras are path algebras associated to higher-rank graphs, and generalize the Leavitt path algebras. We study the center of a simple Kumjian–Pask algebra and characterize commutative Kumjian–Pask algebras

Keywords: Kumjian–Pask algebra, Leavitt path algebra, higher-rank graph, $k$-graph, center
