Popis:	This paper focuses on a one-dimensional fourth-order nonlinear dispersive partial differential equation for curve flows on a K\"ahler manifold. The equation arises as a fourth-order extension of the one-dimensional Schr\"odinger flow equation, with physical and geometrical backgrounds. First, this paper presents a framework that can transform the equation into a system of fourth-order nonlinear dispersive partial differential-integral equations for complex-valued functions. This is achieved by developing the so-called generalized Hasimoto transformation, which enables us to handle general higher-dimensional compact K\"ahler manifolds. Second, this paper demonstrates the computations to obtain the explicit expression of the derived system for three examples of the compact K\"ahler manifolds, dealing with the complex Grassmannian as an example in detail.
