Alexis Poindron Public Lecture "Influence Processes"


On February 10, at 7:00 pm, a guest speaker, Alex Poindron , invited by the ISU School of Technology, will hold an online public lecture on "Influence Processes".

About the lecture

If we take a look at the universe, whether it is particles, genes and/or economic agents, we will see that it is made up of interacting components. Complex systems theory studies how local interactions generate global dynamics that we can transform into the network perspective. This allows us to explore issues such as: How do individual behaviors shape economic and social events? Can an individual cause a mass disorder, and/or can a single sick patient make sick the whole society? How does the network structure determine the speed of disease spread? Similarly, how is the viewpoint spread in the society according to the structure of this society? How fast or slow are new technologies adopted, etc.

The following issues will be discussed at the lecture:

  • Influence models in continuous opinion formation - French/DeGroot model. Is consensus possible and is it ineluctable? If yes, how long does it take?
  • Epidemic networks - the spread of epidemics mainly depends on two parameters: the infectivity of pathogenic agents and the structure of the network;
  • One choice barrier models - introducing a specific cases of influence models;
  • Outdoor games networks - introducing Ballester et al. model.
  • Crime networks - dynamics of discrete binary opinion. Variable opinion models are especially useful for biological phenomena, gene interactions, disease recovery and so on.
