Abstract: In this talk, I will present two classes of numerical methods for solving the stochastic control problems (or HJB equations/variational inequalities) arising in finance and insurance. The first one is the finite difference method (FDM) with iteration policy for solving the HJB equations and variational inequalities arising in regime switching optimal investment. The second one is the delta family approach for the two-dimensional stochastic control (and stopping) problems from the optimal investment and reinsurance-investment, including the case under the classical and rough Heston stochastic volatility models, and stochastic local volatility models such as the stochastic alpha beta rho (SABR) models. The convergence for the first one is obtained, while not for the second one, although it is relatively easier to implement.
