Abstract: Consider the Bowen-Series transform $ T$ associated with an even corners fundamental domain of finite volume for some Fuchsian group $ \Gamma $. We prove a generic invariance result that abstracts Series' orbit-equivalence theorem to families of relations on the unit circle. Two applications of this result are developed. We first prove that $ T$ satisfies a strong-orbit equivalence property, which allows to identify its hyperbolic periodic orbits with primitive hyperbolic conjugacy classes of $ \Gamma $. Then, we show thanks to the invariance theorem that the eigendistributions for the eigenvalue $ 1$ of the transfer operator of $ T$ with spectral parameter $ s \in \mathbb{C}$ are in bijection with smooth bounded eigenfunctions for the eigenvalue $ s(1-s)$ of the hyperbolic Laplacian on the quotient $ \mathbb{D} / \Gamma $.
