In this talk we consider zero-sum stochastic differential games both on the finite time horizon and infinite horizon as well as the utility theory in financial mathematics. Firstly, by introducing a stochastic differential game whose dynamics and multi-dimensional cost functionals form a multi-dimensional coupled forward-backward stochastic differential equation with jumps, we give a probabilistic interpretation to a system of coupled Hamilton-Jacobi-Bellman-Isaacs equations. Then, we study a type of zero-sum stochastic differential games with long-run average payoff in which the diffusion term of the dynamics does not need to be non-degenerate, and obtain the existence of the value. Finally, an optimal forward investment problem in an incomplete market with model uncertainty is investigated by using the related zero-sum stochastic differential games. Moreover, the representation of the power robust forward performance process is obtained and the corresponding investment policy for an investor is given.
