Abstract In this note, we revisit Ramanujan-type series for $frac {1}{pi }$ and show how they arise from genus zero subgroups of $mathrm {SL}_{2}(mathbb {R})$ that are commensurable with $mathrm {SL}_{2}(mathbb {Z})$ . As illustrations, we reproduce a striking formula of Ramanujan for $frac {1}{pi }$ and a recent result of Cooper et al., as well as derive a new rational Ramanujan-type series for $frac {1}{pi }$ . As a byproduct, we obtain a Clausen-type formula in some general sense and reproduce a Clausen-type quadratic transformation formula closely related to the aforementioned formula of Ramanujan.

Abstract Let $W_{Gamma} $ be the right-angled Coxeter group with defining graph $Gamma $ . We show that the asymptotic dimension of $W_{Gamma} $ is smaller than or equal to $mathrm{dim}_{CC}(Gamma )$ , the clique-connected dimension of the graph. We generalize this result to graph products of finite groups.
