Fragmentation transitions in multi-state voter models
Adaptive models of opinion formation among humans can display a fragmentation transition, where a social network breaks into disconnected components. Here we investigate this transition in a class of models with arbitrary number of opinions. In contrast to previous work we do not assume that opinions are equidistant or arranged on a one-dimensional conceptual axis. Our investigation reveals det...
متن کاملMultistate Models in Health Insurance
We illustrate how multistate Markov and semi-Markov models can be used for the actuarial modeling of health insurance policies, focussing on health insurances that are pursued on a similar technical basis to that of life insurance. On the basis of the general modeling framework of Helwich (2008), we study examples of permanent health insurance, critical illness insurance, long term care insuran...
متن کاملEarly fragmentation in the adaptive voter model on directed networks.
We consider voter dynamics on a directed adaptive network with fixed out-degree distribution. A transition between an active phase and a fragmented phase is observed. This transition is similar to the undirected case if the networks are sufficiently dense and have a narrow out-degree distribution. However, if a significant number of nodes with low out degree is present, then fragmentation can o...
متن کاملHeterogeneous voter models.
We introduce the heterogeneous voter model (HVM), in which each agent has its own intrinsic rate to change state, reflective of the heterogeneity of real people, and the partisan voter model (PVM), in which each agent has an innate and fixed preference for one of two possible opinion states. For the HVM, the time until consensus is reached is much longer than in the classic voter model. For the...
متن کاملCounterintuitive transitions in multistate curve crossing involving linear potentials
Two problems incorporating a set of horizontal linear potentials crossed by a sloped linear potential are solved analytically and compared with numerical results: (a) the case where boundary conditions are specified at the ends of a finite interval and (b) the case where the sloped linear potential is replaced by a piecewise-linear sloped potential and the boundary conditions are specified at i...
