WebJan 23, 2024 · Recall that a graph manifold is a prime three-manifold admitting a JSJ decomposition into pieces admitting Seifert fibered structures. Theorem 1. Let $Y$ be a closed, connected, orientable graph manifold. If $Y$ is not an L-space then $Y$ admits a $C^ {0}$ coorientable taut foliation. WebAug 20, 2024 · We prove the Singer conjecture for extended graph manifolds and pure complex-hyperbolic higher graph manifolds with residually finite fundamental groups. In real dimension three, where a result of Hempel ensures that the fundamental group is always residually finite, we then provide a Price type inequality proof of a well-known …

WebA manifold of rank n is such set X that for each x ∈ X there exists a neighborhood Hx ⊂ X such that Hx is isomorphic to an open subset of Rn. In this case, the whole X = graph(f) is isomophic to Rn. The definition of a manifold differs, often it is required for the isomophism to be diffeomophism, which is true here as well. WebIt is unknown whether all extended graph manifolds or all higher graph manifolds have residually nite fundamental group, see Section 12.1 in [FLS15]. We show that there are many examples which do have residually nite fundamental group, both in the extended graph mani-fold setting and in the pure complex-hyperbolic higher graph manifold setting.
