Sant’Anna Rahul Ladhania Wenbo Wu Greg Lewis Christian Hansen Mohsen Bayati Nathan Kallus Eoghan O'Neill Davide Viviano Proximity is measured over citations between two papers we both hold, weighted by how heavily one leans on the other, and is symmetric — it does not distinguish citing from being cited. Authors without a profile here are skipped, and a genuinely close colleague can be missing simply because their work is not in our arXiv corpus. Method: docs/06-citations-pipeline.md .
