Self-reinforcing cascades: A spreading model for beliefs or products of varying intensity or quality
Laurent Hébert-Dufresne, Juniper Lovato, Giulio Burgio +3
Models of how things spread often assume that transmission mechanisms are fixed over time. However, social contagions--the spread of ideas, beliefs, innovations--can lose or gain i…
Templating Aggregation
P. L. Krapivsky, S. Redner
We introduce an aggregation process based on \emph{templating}, where a specified number of constituent clusters must assemble on a larger aggregate, which serves as a scaffold, fo…
Charged Aggregation
P. L. Krapivsky, S. Redner
We introduce an aggregation process that begins with equal concentrations of positively and negatively `charged' monomers. Oppositely charged monomers merge to form neutral dimers.…
Catalytic Coagulation
P. L. Krapivsky, S. Redner
We introduce an autocatalytic aggregation model in which the rate at which two clusters merge to form a cluster is controlled by the presence of a third "catalytic" cluster whose m…
Epidemic Forecast Follies
P. L. Krapivsky, S. Redner
We introduce a simple multiplicative model to describe the temporal behavior and the ultimate outcome of an epidemic. Our model accounts, in a minimalist way, for the competing inf…
Mortality, Redundancy, and Diversity in Stochastic Search
Baruch Meerson, S. Redner
We investigate a stochastic search process in one dimension under the competing roles of mortality, redundancy, and diversity of the searchers. This picture represents a toy model…
