Fortunately, the concept of the characteristic function generalizes easily to random fields and is referred to as the characteristic functional in this context. After a brief discussion of probability ...

In this paper, the characteristic function method is applied to seek traveling wave solutions of nonlinear partial differential equations in a unified way. We consider the Wu-Zhang equation (which ...

GMM inference procedures based on the square of the modulus of the model characteristic function are developed using sample moments selected using estimating function theory and bypassing the use of ...
