  3. In this dissertation, we study the global topological classification and coefficient conditions of the plane homogeneous fifth polynomial differential system the main techniques used in this thesis includes the methods of the global structure and coefficient conditions of the plane homogeneous quadratic and cubic system mentioned in the paper [ 1 ] of professor ye yanqian, and the paper [ 2 ] of professor li xue min, also includes the idea to high - order critical point of professor zhang zhifen, lu yulin and han yuliang etc. due to the degree of polynomial in the right of equal - sign crease, when we discuss the global structure, the more special directions, the more difficulty in drawing phase portraits of this system

    本文主要討論一類平面微分系統的全局拓撲結構及系數條件。借鑒了文獻[ 1 ]葉彥謙教授對平面系統的全局結構及系數條件和文獻[ 2 ]李學敏教授對平面系統的全局結構及系數條件的研究方法,同時綜合了張芷芬教授、陸毓麟教授、韓玉良教授等人對高奇點的研究思想進行討論。這樣,由於等號右邊數的增加,討論系統的全局結構時,可能出現的特殊方向就會增加,在作全局相圖時,難度增大了。
  4. ( 1 ) based on two types of riccati equations, two kinds of new methods are proposed to obtain solutions of nonlinear differential equations. twelve families of exact solutions of wbk equation are found by using one of two methods ; ( 2 ) the homogeneous balance method is improved cind investigated to ( 2 + l ) - dimensional broer - kaup equation such that many families of new solutions are derived. ( 4 ) based on the isospectral lax pair of riccati form for generalized kdv equation with the force term, new darboux transformation and solitary - like wave solutions and rational solutions are obtained ; ( 4 ) by constructing darboux transformation and the superposition formula of generalized variable coefficients kdv equation with the force term, new single solitary - like wave solutions, double solitary - like wave solutions and rational solutions are found for ( 2 + l ) - dimensional generalized kp equation

    第二章和第三章考慮非線性偏微分方程的精確解的構造:首先給出了c - d對和c - d可積系統的基本理論,然後在第三章中具體研究了它們的應用: ( 1 )基於兩種riccati方程,提出了兩種新的求解非線性微分方程更解的方法,利用其中的一種方法,得到了wbk方程的12組精確解; ( 2 )對子衡法進行改進,以致於獲得了( 2 + 1 ) -維broer - kaup方程的很新解; ( 3 )基於帶有外力的廣義kdv方程的riccati形的非等譜lax對,提出了該方程的一個新的darboux變換,利用該變換,得到了新的類孤波解和有理解; ( 4 )通過構造了帶有外力的變系數kdv方程的darboux變換及疊加原理,獲得( 2 + 1 ) -維廣義kp方程的新的類單孤波解、雙類孤波解和有理解。
