We study an infinite-dimensional Black—Scholes—Barenblatt equation which is a Hamilton—Jacobi—Bellman equation that is related
to option pricing in the Musiela model of interest rate dynamics. We prove the existence and uniqueness of viscosity solutions
of the Black—Scholes—Barenblatt equation and discuss their stochastic optimal control interpretation. We also show that in
some cases the solution can be locally uniformly approximated by solutions of suitable finite-dimensional Hamilton—Jacobi—Bellman
equations. 相似文献
