The intersection of connection graphs and discrete optimal transport presents a novel paradigm for understanding complex graphs and node interactions. In this paper, we delve into this unexplored territory by focusing on the Beckmann problem within the context of connection graphs. Our study establishes feasibility conditions for the resulting convex optimization problem on connection graphs. Furthermore, we establish strong duality for the conventional Beckmann problem, and extend our analysis to encompass strong duality and duality correspondence for a quadratically regularized variant. To put our findings into practice, we implement the regularized problem using gradient descent, enabling a practical approach to solving this complex problem. We showcase optimal flows and solutions, providing valuable insights into the real-world implications of our theoretical framework.
