Query: An energy-based interaction model for population opinion dynamics with
  topic coupling   We introduce a new, and quite general variational model for opinion dynamics
based on pairwise interaction potentials and a range of opinion evolution
protocols ranging from random interactions to global synchronous flows in the
opinion state space. The model supports the concept of topic "coupling",
allowing opinions held by individuals to be changed via indirect interaction
with others on different subjects. Interaction topology is governed by a graph
that determines interactions. Our model, which is really a family of
variational models, has, as special cases, many of the previously established
models for the opinion dynamics. After introducing the model, we study the
dynamics of the special case in which the potential is either a tent function
or a constructed bell-like curve. We find that even in these relatively simple
potential function examples there emerges interesting behavior. We also present
results of preliminary numerical explorations of the behavior of the model to
motivate questions that can be explored analytically.
