Classical Cheeger inequalities for finite reversible Markov processes make a link between the spectral gap and the connectivity constants, which are obtained by minimizing isoperimetric-type quotients over decompositions of the state space into two disjoint parts. The purpose of the paper is to obtain such inequalities between the whole spectrum and decompositions of the state space into several parts, when the underlying graph is a cycle.NEWLINENEWLINE Furthermore, the relation between an intermediate Dirichlet connectivity spectrum and the nodal domains of the eigenfunctions of the finite reversible Markov process under consideration is investigated.
