-algebraicity of zeta functions of sofic-Dyck shifts
arXiv:1501.05843
Abstract
We prove that the multivariate zeta function of a sofic-Dyck shift is the commutative series of some visibly pushdown language. As a consequence the zeta function of a sofic-Dyck shift is the generating function of a visibly pushdown language and is thus an -algebraic series.
