A novel framework to analyze complex network dynamics
Matthieu Gilson, Nikos E Kouvaris, Gustavo Deco +1
Graph theory constitutes a widely used and established field providing powerful tools for the characterization of complex networks. The intricate topology of networks can also be i…
Hopping in the crowd to unveil network topology
Malbor Asllani, Timoteo Carletti, Francesca Di Patti +2
We introduce a nonlinear operator to model diffusion on a complex undirected network under crowded conditions. We show that the asymptotic distribution of diffusing agents is a non…
Physical models from noncommutative causality
Nicolas Franco
We introduced few years ago a new notion of causality for noncommutative spacetimes directly related to the Dirac operator and the concept of Lorentzian spectral triple. In this pa…
Seven Hints for Primordial Black Hole Dark Matter
Sebastien Clesse, Juan García-Bellido
Seven observations point towards the existence of primordial black holes (PBH), constituting the whole or an important fraction of the dark matter in the Universe: the mass and spi…
The Lorentzian distance formula in noncommutative geometry
Nicolas Franco
For almost twenty years, a search for a Lorentzian version of the well-known Connes' distance formula has been undertaken. Several authors have contributed to this search, providin…
A note on preconditioning weighted linear least squares, with consequences for weakly-constrained variational data assimilation
Serge Gratton, Selime Gürol, Ehouarn Simon +1
The effect of preconditioning linear weighted least-squares using an approximation of the model matrix is analyzed, showing the interplay of the eigenstructures of both the model a…
