L. Kullmann, J. Kertesz
We consider a preferential growth model where particles are added one by one to the system consisting of clusters of particles. A new particle can either form a new cluster (with p…

Identification of clusters of companies in stock indices via Potts super-paramagnetic transitions
L. Kullmann, J. Kertesz, R. N. Mantegna
The clustering of companies within a specific stock market index is studied by means of super-paramagnetic transitions of an appropriate q-state Potts model where the spins corresp…
