    • Zero rest-mass fields and the Newman-Penrose constants on flat space 

      Gasperin, E; Kroon, JAV (AIP Publishing, 2020-12-01)
      Zero rest-mass fields of spin 1 (the electromagnetic field) and spin 2 propagating on flat space and their corresponding Newman–Penrose (NP) constants are studied near spatial infinity. The aim of this analysis is to clarify ...
    • Zero-one Schubert polynomials 

      Fink, A; Mészáros, K; St. Dizier, A (Springer (part of Springer Nature), 2020)
      We prove that if σ∈Sm is a pattern of w∈Sn, then we can express the Schubert polynomial 𝔖w as a monomial times 𝔖σ (in reindexed variables) plus a polynomial with nonnegative coefficients. This implies that the set of ...
    • Zoo Guide to Network Embedding 

      Baptista, A; Sanchez-Garcia, R; Baudot, A; Bianconi, G (IOP Publishing, 2023)
      Networks have provided extremely successful models of data and complex systems. Yet, as combinatorial objects, networks do not have in general intrinsic coordinates and do not typically lie in an ambient space. The process ...
