From Technical Feasibility to Substitutability: A Geometric Theory of Differentiation
Aldric Labarthe, Yann Kerzreho
We study horizontal differentiation when the set of feasible products is a structured subset of the Lancasterian characteristics space. Modeling this set as a compact Riemannian ma…

Homogenization of Multi-agent Learning Dynamics in Finite-state Markov Games
Yann Kerzreho
This paper introduces a new approach for approximating the learning dynamics of multiple reinforcement learning (RL) agents interacting in a finite-state Markov game. The idea is t…

Generating social networks with static and dynamic utility-maximization approaches
Aldric Labarthe, Yann Kerzreho
In this paper, we introduce a conceptual framework that model human social networks as an undirected dot-product graph of independent individuals. Their relationships are only dete…
