Generalized Graph Manifolds and the Singer Conjecture
Dr. Michael Hull
Assistant Professor of Mathematics
University of North Carolina-Greensboro
“We prove the Singer Conjecture for extended graph manifolds (in the sense of Frigerio-Lafont-Sisto) and pure complex-hyperbolic higher graph manifolds (in the sense of Connell-Suarez-Serrato) with residually finite fundamental group. The proof is based on Price inequalities developed by Di Cerbo-Stern. This is joint work with L. Di Cerbo.”
