Johannes Heiny, Tiefeng Jiang, Tuan Pham +1
We investigate the extreme values of a sparse and equicorrelated Gaussian field on a triangle: the correlations on every vertical or horizontal line are all equal to a parameter $r…

Explanations of polarization often rely on one of the three mechanisms: homophily, bounded confidence, and community-based interactions. Models based on these mechanisms consider t…

Mean-field theory of the general-spin Ising model
Lourens Waldorp, Tuan Pham, Han L. J. van der Maas
Motivated by modelling in physics and other disciplines, such as sociology and psychology, we derive the mean field of the general-spin Ising model from the variational principle o…
