Convergence to Nash equilibria in monotone games and their characterization
It appeared recently that concepts of game theory, Nash equilibrium in particular, are useful in constructing efficient AI agents playing complicated board games. We are going to present Regularized Nash Dynamics (R-NaD), an algorithm that …

Structure and methodology of economics
Case study: Solow growth model - how to receive the Nobel prize for one equation -model understandable by a second-year student. Observing "stylised facts" -> building model ->predicting behaviour in rare events -> testing on …

Landau—Ginzburg Functional for the Contrarian Voter Model
We investigate a simple Landau—Ginzburg field theory for the contrarian voter Ising model proposed by Devauchelle et al. [Phys. Rev. E 109, 044106 (2024)], with the aim of explaining the occurrence of tight margin of …

Split Societies, Elections, and Polls
In modern democracies, the outcomes of elections and referendums are often strikingly close to evenly split. To explain this phenomenon, we propose a simple model of binary voting inspired by the Ising model. Voters are …

One-sided versus two-sided aspects in Dyson models
We discuss a number of recent results about Dyson models, which are ferromagnets with polynomially decaying interactions. We show that at low temperatures their Gibbs measures (which have continuous two-sided conditional probabilities) are not g-measures …
