A dynamical network approach to uncovering hidden causality relationships in collective neuron firings
Błażej Ruszczycki, Zhenyuan Zhao, Neil F. Johnson
We analyze the synchronous firings of the salamander ganglion cells from the perspective of the complex network viewpoint where the network's links reflect the correlated behavior…
Computational modeling of collective human behavior: Example of financial markets
Andy Kirou, Blazej Ruszczycki, Markus Walser +1
We discuss how minimal financial market models can be constructed by bridging the gap between two existing, but incomplete, market models: a model in which a population of virtual…
Target Space Duality III: Potentials
Orlando Alvarez, Blazej Ruszczycki
We generalize previous results on target space duality to the case where there are background fields and the sigma model lagrangian has a potential function.
Target Space Duality: The Dilaton Field
Orlando Alvarez, Blazej Ruszczycki
Classical target space duality transformations are studied for the non-linear sigma model with a dilaton field. Working within the framework of the Hamiltonian formalism we require…
