Monic representations of finite higher-rank graphs

초록

In this paper, we define the notion of monic representation for the -algebras of finite higher-rank graphs with no sources, and we undertake a comprehensive study of them. Monic representations are the representations that, when restricted to the commutative -algebra of the continuous functions on the infinite path space, admit a cyclic vector. We link monic representations to the -semibranching representations previously studied by Farsi, Gillaspy, Kang and Packer (Separable representations, KMS states, and wavelets for higher-rank graphs. J. Math. Anal. Appl. 434 (2015), 241-270) and also provide a universal representation model for non-negative monic representations. © Cambridge University Press, 2018.
