Socio-economical dynamics as a solvable spin system on co-evolving networks

Socio-economical dynamics as a solvable spin system on co-evolving networks

We consider social systems in which agents are not only characterized by their states but also have the freedom to choose their interaction partners to maximize their utility. We map such systems onto an Ising model in which spins are dynamically coupled by links in a dynamical network. In this model there are two dynamical quantities which arrange towards a minimum energy state in the canonica...

Strings as perturbations of evolving spin-networks

A connection between non-perturbative formulations of quantum gravity and perturbative string theory is exhibited, based on a formulation of the non-perturbative dynamics due to Markopoulou. In this formulation the dynamics of spin network states and their generalizations is described in terms of histories which have discrete analogues of the causal structure and many fingered time of Lorentzia...

Dynamics in Co-evolving Networks of Active Elements

We investigate the co-evolving dynamics in a weighted network of various dynamical elements, in which the state of the elements at the nodes and the weights of the links interact with each other. First, we examine the network of phase oscillators with various local, bottom-up rules for the weight of the link, and next investigate the recurrent networks of neurons with the global, top-down learn...

The Ecology of Participants in Co-evolving Socio-technical Environments

The traditional notions of developer and user are unable to reflect the fact that many software systems nowadays are developed with the participation of many people of different interests and capabilities. The sharp distinction between users and developers gets blurred. Many researchers have used different concepts such as enduser developer, prosumer, pro-am to describe those new in-between rol...
