The paper "Stable Homology as an Indicator of Manifoldlikeness in Causal Set Theory" by Associate Professor of Physics Seth Major and collaborators David Rideout (Perimeter Institute, Waterloo, Canada) and Sumati Surya (Raman Research Institute, Bangalore, India) was published Friday, Aug. 14, in the journal Classical and Quantum Gravity. The paper is the third in a series on the recovery of the shape of space, or "topology," (does it look like a ball, a donut, or something else?) from point-like building blocks and their causal relations. The paper reported on numerical studies showing that the technique of recovering the shape of space on a discrete, ordered set works well, even in situations in which earlier analytical work fails to prove that the method is successful.
