Distributed games with jumps: An $\alpha$-potential game approach
The α-potential game framework reduces α-Nash equilibria in distributed jump diffusion games to finite-dimensional control problems, with explicit polynomial and logarithmic α decay rates for asymmetric networks and Nash equilibrium construction for heterogeneous mean-variance portfolio games.
