The effect of compatibility and heterogeneous adoptability in contagion processes — Byungjoon Min and •Maxi San Miguel — Instituto de Fisica Interdisciplinar y Sistemas Complejos (CSIC-UIB), Campus Universitat Illes Balears, E-07122 Palma de Mallorca, Spain

While competition and compatibility of multiple contagious entities and heterogeneous adoptability of agents are omnipresent in social contagions, so far these factors are overlooked in traditional models of contagion processes. Here, we study generalized contagion processes in two directions: i) unifying simple and complex contagions reflecting heterogeneous adoptability and ii) considering competition and compatibility among multiple transmittable entities. For a generalized contagion model unifying simple and complex contagion processes, we find a rich variety of phase transitions such as continuous and discontinuous phase transitions, criticality, tricriticality, and double transition. We also examine the role of dual users who possess multiple contagious technologies simultaneously, and find that the compatibility induced by the dual user facilitates spread of innovation and extinction of preexisting technology.
