    奇攝動轉向點問題是來自量子力學及其他物理力學中的重要問題,特別對非的轉向點問題,已有的結果甚少,文章研究一類具有轉向點的擬的角層現象,在適當的假設條件下,利用微分不等式方法證明了當其退解在( 0 , 1 )內某些點上一階導數不連續時解的存在,並得到了解的按分量的一致有效的漸近估計。
  3. Especially, when the isocline of x is monotone decreasing in 0 < x < 1, the svstem has no limit cycle and is globally stable ; next, we construct a saddle bifurcation at the boundary equilibrium and a degenerated bogdanov - takens bifurcation at the interior equilibrium by choosing appropriate parameter values in the following two sections, where our work are based on the theory of central manifolds and normal torms. we prove that is a codimention 3 focus - type equilibrium. system ( 6. 1 ) will have two limit cycles at some appropriate bifurcation parameter values, and have homoclinic or double - homoclinic orbits at some other appropriate bifurcation parameter values ; at last, we study the qualitative properties of the system at infinite in the poincare sphere

    因為在( 0 , 0 )點處沒有定義,這給研究其在( 0 , 0 )附近的動力學質帶來了困難,我們應用文獻[ 17 ]中關于研究非方程奇點的列理論和方法,圓滿解決了這一問題,給出了第一象限內當t +或t -時,在全參數狀態下的軌趨于( 0 , 0 )點的所有可能情況,其相圖也得以描繪;並且,不存在極限環的幾個充分條件我們也予以列出,當x的等傾在0 x 1范圍內遞減時,不存在極限環,全局漸近穩定;然後,我們以中心流形定理和正規型方法為主要工具,巧妙選擇參數,分別構造了一個余維2的鞍點分岔和一個余維3退bogdanov - takens分岔,證明了平衡點是余維3的焦點型平衡點,存在參數, m ,的值使得( 6 . 1 )有兩個極限環,還存在參數, m ,的另外值使得( 6 . 1 )有同宿軌或雙同宿軌。
