An $Ω$-Result for the Counting of Geodesic Segments in the Hyperbolic Plane

Abstract: Let $\Gamma$ be a cocompact Fuchsian group, and $l$ a fixed closed geodesic. We study the counting of those images of $l$ that have a distance from $l$ less than or equal to $R$. We prove an $\Omega$-result for the error term in the asymptotic expansion of the counting function. More specifically, we prove that the error term is equal to $\Omega_{\delta}\left(X^{1/2}\left(\log{\log{X}}\right)^{1/4-\delta} \right)$, where $X=\cosh{R}$.
