文摘We introduce a new type of path-dependent quasi-linear parabolic PDEs in which the continuous paths on an interval [0, t] become the basic variables in the place of classical variables(t, x) ∈ [0, T ] × Rd. This new type of PDEs are formulated through a classical BSDE in which the terminal values and the generators are allowed to be general function of Brownian motion paths. In this way, we establish the nonlinear FeynmanKac formula for a general non-Markovian BSDE. Some main properties of solutions of this new PDEs are also obtained.
