Abstract: This talk will address a problem arising in financial modeling with stochastic differential equations (SDEs). A characterization theorem will be derived in which we establish a new link from SDEs to nonlinear parabolic PDEs. Starting from the necessary and sufficient conditions of the path-independence of the density of Girsanov transform for SDEs, we are able to derive a characterization by means of nonlinear parabolic equations of Burgers-KPZ type. Extensions to the cases of degenerated SDEs, jump SDEs, as well as to (infinite dimensional) SDEs on separable Hilbert spaces will be discussed. A perspective to stochastically deformed dynamical systems will be briefly considered.
