*讲座内容简介：
In the talk, a family of solutions of piecewise constant vorticity to several fluid systems will be introduced. The equations of the contour dynamics under different geometrical situations will be formulated. Those equations are usually nonlinear nonlocal dispersive equations. The global well-posedness of the solutions will be proved under certain assumptions.
