摘要: The generalized KdV equation ut+auus+μusℑ+εusℑ=0[1] is a typical integr-able equation. It is derived studying the dissemination of magnet sound wave in coldplasma[2], Ihe isolated wave in transmission line[3], and the isolated wave in the bound-ary surface of the divided layer fluid[4]. For the characteristic problem of the gene-ralized KdV equation, this paper, based on the Riemann function, designs a suitablestructure, then changes the characteristic problem to an equivalent integral and dif-ferential equation whose corresponding fixed point, the above integral differential equ-ation has a unique regular solution, so the characteristic problem of the generalizedKdV equation has a. unique solution. The iteration solution derived from the integraldifferential equation sequence is uniformly convegent in Ω.
