In this paper, the Fokas unified method is used to analyze the initial-boundary value for the ChenLee-Liu equation i?tu + ?xxu-i|u2|?xu = 0 on the half line(-∞, 0] with decaying initial value. Assuming that the solution u(x, t) exists, we show that it can be represented in terms of the solution of a matrix Riemann-Hilbert problem formulated in the plane of the complex spectral parameter λ. The jump matrix has explicit(x, t) dependence and is given in terms of the spectral functions{a(λ), b(λ)}and{A(λ), B(λ)}, which are obtained from the initial data u0(x) = u(x, 0) and the boundary data g0(t) = u(0, t), g1(t) = ux(0, t), respectively. The spectral functions are not independent,but satisfy a so-called global relation. 展开更多
